9 Best Wax for RV Fiberglass Reviews

1. Meguiar’s M-4965 MG RV Fiberglass Oxidation Removal

If you want to clean or restore a vehicle, Meguiar’s usually has the exact right product for the job. An excellent example of this company’s fantastic quality would be Meguiar’s M-4965 MG RV Fiberglass Oxidation Removal Kit. It’ll have no problem getting your fiberglass RV back to something that you can show off.

The kit offers these results by providing buyers with a high gloss polish, an oxidation remover, and an excellent RV wax. I couldn’t believe how effective each of these products was for their intended purposes.

For instance, the high gloss polish made my motorhome shine like it was brand new. I would recommend using it to anyone wondering how to polish RV fiberglass surfaces. It was everything that I could’ve imagined and more.

The oxidation remover didn’t have any issues keeping up with these results, either. It did a phenomenal job removing water spots and oxidation from my rig’s exterior. Other buyers felt the same way as they filled this kit’s reviews with praise for its oxidation removal skills.

As for the included wax, it’ll offer durable protection and keep your rig free from any future issues. I haven’t had any problems with the shine wearing off yet or picking any new surface problems. Buyers should expect their rig’s fiberglass surface to stay shiny for a long, long time.

I only wish buyers had a few choices about the quantity of each included product. It seems like a missed opportunity by Meguair’s to make this kit more convenient. But it’s a small thing to complain about and nothing drastically problematic.

In any case, I don’t see a single other reason why someone wouldn’t buy this kit. It meets all the requirements an RVer could ever want in an oxidation remover, polish, or wax.

2. Meguiar’s M6732 RV One-Step Compound

RV owners shouldn’t be too shocked to see another product from this brand on our list. Meguiar’s M6732 RV One-Step Compound manages to stand out even among their other products with its several impressive features.

An excellent example would be its application process. It’s capable of aggressively cleaning and polishing any fiberglass or gel-coat RV surface in one-step. You should expect the surface to be clean of any scratches, heavy oxidation, stains, or tough water spots.

Honestly, this product should take care of any surface issues with relative ease. It’ll then replace it with a high-gloss shine that everyone will notice. You can’t ask for much more from wax for gelcoat RV or fiberglass RV surfaces.

Additionally, this wax offers some choices when it comes to the application process. Users can apply it by hand or with a machine, such as a buffer. Its flexibility makes the product a suitable option for both large-scale and small-scale jobs.

You also get quite a bit of the compound as it comes in a 32 oz bottle. Most RVers should get a few jobs done with a single container of this product. RVers can undoubtedly use it on enough surfaces where having some leftover wouldn’t be a bad thing.

But I would recommend using a buffer for larger-scale projects as some customers complained about the amount of elbow grease needed. It’s something to think about before putting money down on this product.

However, the performance quality alone makes this elbow grease more than worth it. It shouldn’t have any trouble getting your RV fiberglass surface to shine as you’ve always imagined. You’ll soon be the source of many motorhome owners’ jealousy around your campground.

3. Collinite RV Fiberglass Cleaner & Wax Combo Pack

The Collinite RV Fiberglass Cleaner & Wax Combo Pack will clean, polish, and restore an RV fiberglass surface without much difficulty.

Collinite’s 920 is easily a contender to be the best RV cleaner for fiberglass surfaces. It’s a mild-cut compound with an effective method of removing light oxidation, discoloration, film, and other tough stains. It’ll also restore your surface’s original coloring with a nice glossy shine.

The Collinite 925 Fiberglass RV Wax will then protect your RV’s surface from future outdoor corrosive elements: UV rays, chalking, salt spray, stains, etc. It’ll offer long-lasting protection that’ll keep your motorhome sparkling for a lengthy time.

Both included products are from a US-based manufacturer, as well. This attribute is an attractive one for several reasons, but mainly, the faster shipping speeds. It’ll undoubtedly arrive at your home much quicker than waxes or cleaners from foreign countries.

RVers won’t be overwhelmed by this combo pack’s price tag, either. It’s more than affordable and costs less than some single product options on this list.

I should also note that these products aren’t only for RV usage. Boat owners have found both the cleaner and wax incredibly effective on their vehicles. You’ll never see me complain about options with multi-purpose abilities.

However, don’t expect this combo pack to do much against heavy oxidation issues. It wasn’t manufactured for heavy-duty rust or corrosion. You’d be better off choosing another product from this list.

But if you have light or no oxidation problems, this option could be a perfect fit. It checks off every other box an RVer could want in their fiberglass wax or cleaner.

4. 3M 36110 Perfect-It Fiberglas Cutting Polish + Wax

If you’re looking for a product with an easy using process, look no further than 3M’s 36110 Perfect-It Fiberglas Cutting Polish + Wax. Buyers will have no issues applying this product on surfaces with either a rotary polisher or by hand.

Once applied, this product gets right to work by effectively removing light oxidation, scratches, swirl marks, and other defects. Multiple customers reported themselves to be shocked by its effectiveness within their respective reviews.

I was also pleased to read about the high-level shine it leaves behind. This shine doesn’t only look pretty, either, as it offers protection against weather, wind, and water. It’ll make sure your RV’s fiberglass surface shouldn’t have problems any time soon.

This polish and wax manages to stay wet longer than most competing products, as well. Therefore, it prevents you from having to stop polishing as often during the application process. It makes the entire task go much faster with a lot less effort needed.

It’s worth noting that this product is another one meant for both gel-coat and fiberglass surfaces. Customers have reported it is more than effective on either surface. 3M did an excellent job creating a wax that almost every RVer will have some use for when traveling.

But even with these great attributes, there’s one slight issue. The price is much higher than you’d expect for a 32 oz bottle. You’ll have to weigh whether it’s convenience or performance that worth spending extra money on.

5. Star Brite Premium RV Fiberglass Restorer and Wax

Any RVer who’s scratching their heads about how to remove oxidation from RV fiberglass should consider buying Star Brite’s Premium RV Fiberglass Restorer and Wax. Its formula was specifically designed to deal with medium or heavy oxidation issues.

You won’t have any problems with the application process, either. Multiple customers reported it taking a lot less effort than similar products available. As someone who hates manual labor, this attribute certainly caught my attention.

I was also thrilled to see users have a choice about whether they want to apply it by hand or with a buffer. It makes the product a more viable option for various fiberglass surface restoration jobs onboard an RV. The 32 oz bottle certainly doesn’t hurt its case, either, as you should get multiple uses out of it.

Its performance quality is more than any RVer could imagine, as well. This restorer and wax will offer a top-notch shine while providing excellent protection for several issues. You won’t have to worry about sun damage or any stains with this product protecting the surface.

This product provides excellent water-repelling abilities, too, which will be crucial for the subsequent cleaning sessions. It’ll make those future cleanup tasks much more manageable than they were before applying this restore and wax.

I only wish it worked on more surfaces as it’s designed explicitly for fiberglass and nothing else. Honestly, it’s a shame because the results it provides are top-notch. I would love to use it on oxidation issues present on a few other surfaces within my motorhome.

But this restorer and wax is highly effective at its intended purpose. Sometimes, you can’t ask for much more than that when doing product research. RVers with oxidation issues on fiberglass surfaces wouldn’t be doing themselves a massive disservice to overlook this one.

6. TR Industries Gel-Gloss RV Polish and Protector

TR Industries’ Gel-Gloss RV Polish and Protector makes polishing and protecting RV surfaces an one-step task. Its formula includes both potent protective agents and carnauba waxes to accomplish these two tasks simultaneously.

You’ll get a significant amount of usage from this multi-purpose product, as well. It’s proven to be effective on all acrylic, cultured marble, and fiberglass surfaces. Product versatility is something that I’m always looking for in any cleaning product.

Its performance also more than lives up to most people’s expectations. This product will have no trouble getting rid of water spots and prevent those pesky build-ups. Plus, it does a solid job at removing oxidation, which tends to be a massive issue for RVers.

I was pleased with the variety of quantity choices, too, as buyers can pick from 16 oz, 64 oz, and 128 oz containers. It makes the product a lot more convenient than most other options. You also have to love their affordable price tags.

More importantly, the product’s shine quality is outstanding. It should bring new life to whatever surfaces, whether interior or exterior. Multiple customers even reported it being a helpful cleaning product for their kitchen sinks.

But it’s important to make sure this product is suitable for your needs. There isn’t a return policy as customers can’t ship it back because of the formula’s ingredients. If you buy this product, expect to be stuck with it, whether you need it or not.

I’d be more than happy to be stuck with it, though, as it fits my needs perfectly. I couldn’t recommend this product enough to my fellow RVers. It’ll end up being one of the most used cleaning products onboard your RV, thanks to its staggering versatility.

7. Star Brite Premium RV Polish 75732 Ultimate Wax

Star Brite Premium’s RV Polish 75732 Ultimate Wax has become a favorite among RVers for its all-season UV protection. It’ll repel stains and any UV rays from causing issues onto a fiberglass surface for an entire year without requiring re-application.

The product makes applying it relatively easy, though, when it’s needed. It doesn’t matter whether you’re doing it by hand or buffer; Star Brite ensured the process was more than manageable. They clearly tried to do their best and make our lives easier as RVers.

You’ll also benefit significantly from its long-lasting shine, which has a little more pop than other options. Neighboring RVers will definitely notice a difference after its application that’ll have them asking, “what wax do you use?”

Users can apply right over old wax or polish for convenience purposes, as well. This attribute makes the using process even more user-friendly than you might’ve expected. It’s just another way this Star Brite can make your life much easier.

More importantly, RVers can use it on multiple surfaces. It can bring its patented high-gloss shine to fiberglass, painted surfaces, and polished metals without any side effects. Honestly, I can think about ten areas within my RV that could benefit from its usage.

But the included 32 oz container might not be enough product for larger RVs. This concern was mentioned in a few customer reviews, which means buyers might have to buy two bottles. This issue could make the price a little too excessive for some RVers.

The performance would be worth dealing with it, though. It does have an excellent shine and easy using process that any RVer can appreciate. Finding a more equipped fiberglass wax would be difficult in today’s market.

8. 303 RV UV Protectant Spray

303’s RV UV Protectant Spray is a perfect option for anyone who has serious sun damage issues. It’ll provide various surfaces with a protective layer that stops those UV rays from causing problems.

Honestly, the number of viable surfaces is rather staggering, including plastic, vinyl, eisenglass, fiberglass, gel coat, rubber, and finished leather. It keeps any of these surfaces from numerous issues ranging from discoloration to cracking.

But it doesn’t only protect them from UV rays as the product also repels stains and dust. As a result, it helps extend the time between cleaning sessions for these surfaces by a significant margin. It makes this protectant spray a very convenient item to have onboard your RV.

I found myself loving the dry matte finish it leaves behind. It brightens your rig’s surfaces without using any toxic chemicals to get those desired results. Instead, it’s a non-toxic, water-based product that you don’t have to hate yourself for using.

Some of its other notable features include several quantity choices, US-made, an easy spray-on application process, and being a rinse-free product. 303 made sure to check off almost every possible attribute an RVer could want in these types of products.

The only issue is a few customers called into question its packaging container. In these cases, it seems spilling the formula was a hard thing to avoid unless being ultra-careful. It’s clear that the product’s bottle design could use improvement.

9. Dicor RP-FCP-1 Fiberglass RV Roof Coating System

If you’re looking to protect your fiberglass RV roof from a wide assortment of issues, Dicor RP-FCP-1 Fiberglass RV Roof Coating System could be an ideal choice. It’s formulated specifically for fiberglass roofs to remove dirt, wax, and road grime from them.

These effective results come from a fast-acting formula that’ll clean and protect your RV roof when traveling from campground to campground. This formula’s biodegradable makeup doesn’t hurt its case, either, for people looking to get a roof-centric product.

You also can’t hate on its using process as many customers reported it to be easy. It comes with detailed instructions that are simple to follow and doesn’t require much RVing experience to understand.

I’d have complete faith in a newbie RVer to get the job done without much help. Buyers can expect its performance to extend onto gel-coated roofs, as well. You should anticipate nothing but high-quality results that’ll make sure your motorhome roof remains in good shape.

The 1-gallon container should also be more than enough to cover a single roof. Some customers even reported being able to coat multiple with a single container. Due to this, the product becomes a little more user-friendly than a person might’ve expected.

I did notice a few customers complain about this product’s smell, though. It seems to have a reputation for producing a foul odor when first spraying it onto a roof’s surface. If you have a sensitive nose, you might want to take some precautions to avoid any unpleasantness.

But the smelly odor looks like the only trait customers can point to as a negative. As an RV fiberglass roof cleaning product, it doesn’t get much better than this one. It’ll help ensure the surface remains in good condition for many years.

3M RV Clean & Shine Wax (Outdated)

Our final wax, 3M RV Clean & Shine Wax, would be a perfect choice for RVers with small fiberglass surface restorations. It features a spray-on cleaner that makes using the product much more manageable than others, especially for smaller jobs.

You can then expect its performance to be quite effective against various ailments. It’s known to remove films, residues, and other minor contaminants without much trouble. It ends up being a lot more useful than most other spray-on waxes or cleaners.

RVers will find it helpful inside the rig, too, as it can work on various surfaces. It was created for use on fiberglass, marine topside paint, painted aluminum, and gel coat. You just spray it on, and a shine will come forth within minutes.

It’s also worth noting that these surfaces can either be dry or wet. Users can apply the wax onto both and still expect the same results. It makes for a simple, effective using process that anyone can do with ease.

I was impressed by how little effort is needed to get high-quality results, as well. There’s minimal elbow grease required to get rid of those surface contaminants haunting your RV’s fiberglass. Many customers alluded to this same benefit in their reviews, as it seems to outpaces other waxes with this quality.

You should love its versatility when it comes to effectiveness on certain vehicles. Boat and jet ski owners often find themselves adoring this product’s overall convenience and quality. It’s perfectly suited for these smaller transport vehicles.

Buyers shouldn’t expect this product to affect oxidation issues in the slightest. It’s more for those lighter, less problematic concerns like streaks, dirt, and residues. In those cases, this spray-on cleaner will do the job without any additional help or products.

Protect All RV Fiberglass Oxidation Remover (Outdated)

Customers who want to bring the shine back to any vehicle should take a long look at Protect All RV Fiberglass Oxidation Remover and Color Restorer. It’s shown to be effective on RVs, cars, trucks, boats, and much more.

The formula’s effectiveness comes from its ability to clean, polish, and seal in a single step. It’ll then remove any oxidation issues and restore the color/surface lying underneath. It’s truly an excellent product to have when traveling around in an RV.

Users can also apply it onto gel coats, fiberglass, polyurethane painted aluminum, and enamel without issue. It’ll add a protective layer onto all of them to ensure the shine is long-lasting and future damage doesn’t occur.

The 64 oz container should be more than enough to cover even a massive Class A RV, as well. You’ll probably even have some leftover to use on other jobs inside or outside your rig. It makes this choice an intriguing option for anyone looking to avoid spending money on multiple cleaning products.

I expected the product to be a little more expensive than this price given its available quantity size. But this option ended up being pretty affordable compared to other choices. I might even consider it a bargain considering the performance results.

But if you’re looking to buy wax for RV decals, consider it more. Its formula is a bit too strong for this type of work, as a few customers reported in their reviews. You’d be better off choosing anything else as this product would damage them.

Aside from the decal issue, there isn’t anything else to complain about with this product. It does the job effectively for an affordable price and works on multiple surfaces.

TR Industries Gel-Gloss RV Cleaner and Wax (Outdated)

The TR Industries’ Gel-Gloss RV Cleaner and Wax offers exceptional performance thanks to its top-tier formula that’s infused with carnauba wax and UV protectors. It’ll ensure the surface becomes free of scratches, oxidation and protected from future issues.

You can actually expect a whole year of protection. In other words, there will be no need to reapply anytime soon. It makes the product a dream come true for people like myself who despise doing maintenance tasks.

I was also pleased to see this product’s 100% biodegradable. As a result, its usage will bring no damage to our planet and won’t cause any dangerous situations. It’s a massive benefit for me because my clumsiness is well-documented as I spill almost everything.

Most buyers tend to note its effectiveness against black streaks, as well. Anyone with excessive black streak issues would be doing themselves a massive favor by buying this product. It should take care of them without breaking a sweat.

Aside from those features, it has several familiar ones discussed in our previous reviews. Some of them include a one-step application process, multiple buying quantities, favorable price tags, and boat usability. It manages to cover a lot of bases for would-be RVer usage.

I was a little surprised by a few customers mentioning it had issues dealing with bug-related surface problems. But you can likely chalk this up to human error, as other buyers stated it did well removing them.

But it’s a minor point anyway, considering bugs aren’t the biggest fiberglass surface problem out there. You’ll be more than happy with how it deals with the other more pressing concerns like oxidation or scratches.

Wax for Fiberglass Buyer’s Guide


Certain vital elements will affect what option becomes the most suitable fiberglass wax for your needs. You should have a deep understanding of these factors to make a final decision. I’ll dive into these vital elements below to ensure this process becomes effortless and hassle-free.

  • Product Convenience

Product convenience is essential in every buying decision. Purchasing wax for RV fiberglass surfaces isn’t any different. One of the first things to look out for would be whether each option has a spray-on nozzle.

As you can imagine, this design feature makes using wax a lot easier. You should also look into whether the solution’s usable with compatible machines, such as buffers. It would allow the entire process to become faster and less taxing.

Both these convenient aspects can have a massive impact on the buyer’s satisfaction. It’s always imperative to think about what your ideal experience with wax looks like before spending any money. If you do, it becomes easier to search for an option capable of meeting those expectations.

I should also note that high-quality fiberglass wax for RV usage will put your convenience at the forefront. It will not be a complex or challenging product known for causing people a great deal of frustration.

In other words, the process of cleaning, restoring, and protecting your RV fiberglass surfaces should only be a few steps at most.

  • UV Protection

Some RVers don’t consider how much damage the sun can do to their rig’s fiberglass surface. Its UV rays have the power to dismantle an RV’s exterior much quicker than most people often realize.

For instance, overexposure to these harsh UV rays will cause fading, discoloration, and even deterioration. An RVer who fails to protect these surfaces from these concerns could result in their campers looking beat-up and rundown.

It’s also crucial to note fiberglass is more at risk of UV damage than most other surfaces. This material doesn’t have self-restoring abilities, either, which doesn’t help matters. These issues are why getting an RV wax with UV protection is necessary.

  • Length of Protection

Worthwhile fiberglass waxes will offer a large window of protection. In other words, these products won’t require reapplying for an extended period; some even last a year. It’s more convenient to spend your money on these waxes rather than ones that wear off after a month.

Otherwise, you’ll end up wasting a lot more time waxing your RV than expected. I’d suggest relying on customer reviews to get a better sense of each choice’s protection longevity. Companies tend to over-exaggerate their product’s capabilities.

  • Product Versatility

Buyers will want to get the most value possible from their chosen fiberglass wax. Getting an option capable of working on multiple materials and surfaces is an easy way of doing it. Product versatility will always be a massive component of customer satisfaction.

However, this doesn’t mean RVers can’t get significant value from a dedicated wax for fiberglass surfaces. But getting a versatile wax could stop you from spending extra cash on additional cleaners.

Finding these versatile cleaners won’t be too difficult, either. Manufacturers will always refer to the meshable surfaces within each wax’s product description. After all, they don’t want users to be misusing their products.

  • Expiration Date

Wax for fiberglass RV surfaces will come in many different-sized containers. Buyers will choose whether to purchase 16 oz bottles for smaller jobs or 1-gallon containers for more massive tasks like covering a Class A motorhome.

If you intend on buying these larger containers, check their shelf life. You don’t want to spend a lot of money on these products when they’re about to expire. It’s likely you won’t use all the wax on a single job. There might be some leftover, which could be helpful down the road.

Buyers wouldn’t want to throw out this unused as it’s just wasteful. Thus, purchasing one with a more extended shelf life would stop this unnecessary wastefulness.

  • Product Safety

The best RV wax for fiberglass will have gone through numerous safety testing before being put up for sale. It needs to have a potent formula that doesn’t use overly abrasive chemicals that cause dangerous situations.

I’d also recommend sticking with waxes made from biodegradable materials. There’s no reason waxing your RV’s exterior needs to harm our planet. Let’s keep these issues from occurring by buying a solid but safe fiberglass RV wax.

  • Cost

You need to find an effective RV fiberglass wax that’s within your price range. But don’t settle for a cheap product with an ultra-low-cost. Try to select a product with a happy medium between its value and performance quality.

Customer reviews will be a vital resource in finding this middle ground. There’s nothing more helpful when determining a product’s quality than other people’s experiences. Use them to get an informed sense of a wax’s overall capabilities.

RV Wax for Fiberglass FAQs

Since you now have an idea about what’s available, it’s time to discuss a few crucial background topics. The following sections will provide a deeper perception of what fiberglass waxes can offer an RVer who’s traveling the road.

Who is this for?

Fiberglass waxes are meant for motorhome owners with rigs containing fiberglass surfaces. If you use other waxes on these surfaces, it can make them look chalky and cause oxidation. Neither of these outcomes is what any RVer wants.

You’ll instead need a wax that was made to work on fiberglass surfaces. These products are the only way to prevent any long-term surface damage from occurring. Due to this, anyone with a fiberglass RV should buy some.

What are the different types of RV waxes for fiberglass?

RV fiberglass wax is commonly found in three main variations: paste, liquid, and spray-on. I’ll discuss each of them at length below to provide some insight into what one fits your needs. From there, choosing one should be simple.

  • RV Liquid Fiberglass Wax

Liquid fiberglass wax is the most common variant on today’s market. In most cases, liquid wax will be in bottles that make them more convenient for larger jobs. If you intend on waxing a massive rig, this type would be your ideal choice.

  • RV Paste Fiberglass Wax

Paste fiberglass wax requires a bit more effort and time to use than liquid options. It shouldn’t be too shocking to learn that this makes them less popular. But they do come in handy when doing minor repairs on fiberglass surfaces.

  • RV Spray-On Fiberglass Wax

Among the three variants, spray-on fiberglass wax is the easiest to apply. You can find them in small or medium bottles, making them best suited for smaller tasks. I’d recommend this type for a campervan or Class B RV owner.

How do RV waxes for fiberglass work?

Waxes for fiberglass surfaces work in the same way as others. The most trusted wax for fiberglass camper surfaces will make your life easy with a simple, one-step application. These products won’t even require special equipment or tools when doing the jobs. Once applied, they’ll restore your fiberglass surface to its original glory.

Advantages and disadvantages of using RV waxes for fiberglass

As with any product, RV waxes for fiberglass surfaces come with benefits and disadvantages. Let’s look at both sides to confirm whether these products are fitting for you. It’s an easy way to ensure you don’t waste money on something that’s not useful.


  • Eco-friendly
  • Restores shine and color of fiberglass surfaces
  • The best options are multi-purpose
  • Inexpensive way of making your RV look better
  • Some options will provide fiberglass UV protection


  • Some might only be usable on fiberglass
  • Could be more challenging to apply than other waxes
  • Might need a few applications

How often should I wax my RV?

RV owners often debate how much they need to wax their rigs. But honestly, there isn’t a definitive answer. Instead, it’ll depend on how frequently your rig’s exposed to the sun and other harsh natural elements.

For instance, an RV owner who only takes out their motorhome for the summer season and mostly stores it inside doesn’t need to wax it regularly. I imagine once per year should be more than enough to keep the vehicle in good condition.

But once per year isn’t going to work for a year-round RVer. They’ll need to wax their motorhomes more frequently, such as every 4 to 5 months. You could even get away with doing it twice a year, but it’s pushing it.

Can I use RV wax for other applications?

Most RV waxes offer a substantial amount of versatility. In other words, they’ll have no problem covering multiple surfaces and vehicles. That said, never assume an RV liquid or spray wax is suitable for aluminum siding, fiberglass, or other applications without checking its instructions.

RV wax manufacturers are very clear about what surfaces their products can handle. Always check the product’s label to see whether it’s for fiberglass gel coat surfaces, boats, decals, etc. It’s always better to be well-informed and avoid potential issues.

You don’t want to be the person who uses specialized wax for RV gel coat surfaces or polish for fiberglass RV surfaces in another application. It’ll likely create surface damage on your vehicle’s exterior that won’t be easy to address.

How do you restore the shine on a fiberglass RV?

The easiest way to restore your fiberglass RV’s shine is by utilizing a high-quality wax with oxidation removal capabilities. My favorite option would have to be Star Brite’s Premium RV Fiberglass Restorer and Wax.

After all, this product has a stellar reputation for dealing with heavy oxidation and providing an excellent shine. So invest in a wax/restorer like this one and use a preferred tool to apply it on your camper, just make sure it’s soft enough to not leave a scratch on your vehicle.

In my case, I love using a hand pad or sponge for more precision. But some people with more widespread issues may do better with a buffer.

Will vinegar remove oxidation from fiberglass?

In some cases, vinegar does represent a solid DIY oxidation remover for fiberglass surfaces, especially when combined with baking soda. But I wouldn’t count on it to be a miracle worker. For example, it will not return a rusted old camper to its former glory.

Vinegar is much more reliable when dealing with slight or new oxidation issues. These situations are where it can become a usable tool in returning your fiberglass surface’s shine. Otherwise, you’re better off with a more potent product like Meguiar’s M6732 RV One-Step Compound.

Is there a difference between marine wax and RV or car wax?

Marine waxes and RV/car waxes are similar, as many are interchangeable. In fact, various polishes for travel trailer use are advertised as usable on boats. There are even some products that are formulated as dual wax for both applications.

However, there is a difference between strictly marine waxes and only RV/car waxes. It boils down to what they protect these vehicles against. For instance, an RV wax for full-body paint surfaces will be crafted to deal with UV rays and grime as these are what RVs encounter daily.

Marine wax, in contrast, doesn’t have to account for grime and UV rays as much as waxes. Instead, they’ll focus more on water damage and other similar problems. So manufacturers will create their formulas to protect more effectively against marine-specific issues.

Who makes the top-rated RV waxes for fiberglass?

If you’re looking for the top RV fiberglass wax brands, scroll back up to our product review section. Each of those manufacturers has a known reputation for creating the top-rated products in this marketplace.

Do I need to prepare the waxing surface before applying?

An RVer will have to do a little preparation before waxing their rig. The type of prep will end up depending on their chosen product. For instance, people who use pure wax options will need to clean and dry the surface before applying.

But the best wash and wax for fiberglass RV surfaces can get applied directly after wetting the area with a sponge or hose. In any case, I’d advise reading the product’s label to ensure there aren’t extra preparation steps.

What makes RV wax different from normal wax?

Camper waxes will be less abrasive than regular wax. After all, an RV needs a wax that won’t cause scratches or other issues on a sensitive surface, such as a gel-coat or fiberglass.

Any care and maintenance tips?

Follow the instructions located on your wax’s label. It should have everything a person might need to know about using and storing the product. Aside from this, there isn’t much else to talk about regarding RV fiberglass waxes’ care and maintenance.

Where can I buy?

The best place to buy wax for fiberglass RV surfaces would be Amazon. You won’t find a better selection or prices anywhere else. Local department stores like Wal-Mart, Home Depot, or Lowe’s should also have some solid choices.


Finding the best RV wax for fiberglass surfaces shouldn’t be a hassle with this buying guide as a resource. It should make the right choice clear for any RVer who needs a little help. But if you still have a question or two, please use our comment section. I’ll answer as quickly as possible to get you back on track!
