The Best RV Waxes for Fiberglass

Fiberglass is a material wherein glass fiber is reinforced into hard plastic. The result tends to be a flattened sheet used in different applications like recreational vehicles (RVs) and marine vessels.

Although RV fiberglass is quite durable, it’s not impervious to harm. Over time, the accumulated damage can promote long-term and sometimes permanent damage. Prevent these hazards from happening by using the best RV wax for fiberglass.

However, you need to be wary of your purchase. Consider taking a second guess before picking up any wax for fiberglass RV you see sitting on a store shelf. Proper research is key to a valuable purchase, and this guide will help you pick the best fiberglass wax.

Can You Wax Fiberglass RV

Yes, you can wax a fiberglass RV. Many motorhome manufacturers use fiberglass to reinforce these vehicles for optimal durability. But, this material tends to have an appearance that degrades over time.

For instance, oxidation may appear, which tends to be a yellowing of the fiberglass surface. Although it does not immediately ruin the structural integrity of the material, oxidation does not look aesthetically pleasing.

Light to medium cases of oxidation tends to appear as a fading or discoloration of fiberglass. But, extreme cases allow this chemical reaction to create small damages or tears. Fiberglass fibers begin to come apart, and removing those elements may cause irreparable damage.

As such, RV owners are advised to use the right wax for their fiberglass motorhomes the moment they see oxidation and other potential causes of damage on their campers before things get worse.

Best RV Wax For Fiberglass Reviews

1. 3M 09006 Marine Restorer & Wax

Restoring shine and adding extra protection to fiberglass RVs might have become easier, thanks to this marine and recreational vehicle restorer and wax.

It has a unique blend that seems to accomplish most of the essentials when maintaining the style and function of fiberglass surfaces. It can remove filmy residue, rust deposits, exhaust stains, skid marks, and oxidation.

It is quite effective in removing light-to-medium dirt, spot, and stain buildup. But I found that it tends to have some difficulty removing years of filth buildup. Also, it seems to find it challenging to restore deep scratches.

Despite those slight shortcomings, this product can restore the color of fiberglass surfaces. Long-term sun exposure faded some of the colors on my camper.

2. TR Industries WW-128 RV Wash and Wax

This wax for RV fiberglass might be a game-changer, considering its plethora of attractive features may satisfy many needs of different motorhome owners.

For starters, this product is a highly-concentrated formula manufactured using bar soap. Despite its concentrated formulation, the bar soap ingredient means it is also safe enough for humans and the environment. Therefore, it does not have harsh chemicals like phosphate that would otherwise be detrimental to the environment.

This wax also covers three functions in one product: cleaning, protecting, and shining. It removes unclean particulates like dust and dirt, provides extra UV protection, and restores the luster of fiberglass RVs. I should also mention that it did not leave streaks, water spots, or other residues after use.

It is also surprisingly easy to spread. I used a quart of this product, and that amount is sufficient to create about 16 gallons of the solution.

But this is no ordinary RV wash and wax for fiberglass motorhomes as it is possible to use this formula on other surfaces. I used it on materials like rubber, metal, and wood without encountering any significant mishaps.

3. Meguiar’s M5001 RV One Step Cleaner Wax

Meguiar’s RV wax is great for maintaining a camper’s high gloss finish. Applying this product to my vehicle, and I could see its premium luster from a good distance.

This wax for motorhomes also handles three functions in one product. It can clean, polish, and apply UV protection in one RV maintenance session. Aside from protecting fiberglass vehicles from the harsh rays of the sun, I found that this product can also protect against other harmful substances, such as rust, corrosion, and salt.

It does not take an entire weekend to restore the beauty of a camper trailer with this product. It offers a four-step process to wash, clean, protect, and restore fiberglass surfaces.

Its non-abrasive formula makes it relatively safe on other surfaces. I used it on vinyl, rubber, and gel-coated surfaces with minimal to no visible damage signs. It is also possible to use this on marine vessels, perfect for fiberglass boat owners.

The amount is also sufficient to clean, protect, and restore the aesthetics of reasonably large RVs. I used it on a 41-ft. camper, and I still had some left to use for small maintenance sessions.

4. Gel-Gloss GG-64 RV Polish and Protector

This gel-gloss RV wash and wax is a necessity for any camper owner. This product is a beast (for lack of a better word) when cleaning and restoring fiberglass.

But its versatility exceeds that of using it on fiberglass as it is also possible to apply it to other materials. I used it on acrylic, plastic, and cultured marble surfaces, specifically my bathroom’s vanity and kitchen counters, and it did not show signs of dulling or other damages.

On the other hand, I attempted to use this product on other surfaces with polyurethane and lacquer finishes. The finish produced by this wax on those surfaces tends to create a dulling effect. Still, it means that this product can be highly useful in restoring fiberglass, acrylic, plastic, and cultured marble.

With that said, using this product is a breeze. A quick wipe on a clean surface with this fiberglass polish creates desirably shiny outcomes. It also removes water spots, which tend to be an area where many low-quality competitors tend to have difficulty.

It also protects fiberglass and other compatible surfaces from unclean substances. I experienced my camper having better resilience to dirty water buildup than before. It also removes oxidation while restoring the faded color of my vehicle.

5. Car Guys 5841714060 Premium Hybrid Wax

Who to call if a fiberglass RV needs restoring? Many camper owners might answer with the Car Guys and their premium hybrid wax.

Perhaps one of the reasons this wax is the go-to product of many, including myself, is its versatility. I tested in fiberglass, plastic, glass, and painted surfaces and acquired more-than-satisfying results. It created such a brilliant, mirror-like shine that I can see my reflection on the surface after the application.

This full synthetic polymer sealant also has three functions rolled into one product. It acts as a carnauba car wax, polish and sealant to provide durable and long-lasting protection to vehicle surfaces.

The finish produced by this wax also lasted quite a long time. It takes about three to six months per major application. Further, it takes approximately two weeks for minimal applications for routine maintenance procedures. Therefore, this one-gallon container should last me more than three months, depending on the amount I use per application.

Aside from using this wax on my motorhome, I also experimented with its efficacy on other surfaces. I tried it on glass, chrome, and several plastics, all of which produced the same or highly similar results.

6. Protect All 55064 Fiberglass Oxidation Remover

Finding the best wax for fiberglass camper might be tough. But that search might not be as challenging as intended, particularly after chancing upon this specific wax for RV fiberglass.

Unlike some low-quality options, this Protect All wax for fiberglass motorhomes brings optimal convenience to its users. I can confidently say that its one-step application is enjoyable, and this feature can remove different unsightly substances on surfaces, including oxidation, bug stains, and surface scratches.

This product can also restore the color and shine of old RVs. Furthermore, it is both flexible and versatile as I had little to no problem using this wax on different vehicles, such as cars, trucks, and boats.

Although it shines (no pun intended) when used on fiberglass, this product is also usable on other surfaces to restore and maintain a long-lasting, high-gloss shine. I used it on enamel, polyurethane painted aluminum, and gel-coated surfaces without signs of damage.

It’s also possible to use this product on both cleaning and maintenance routines for fiberglass camper trailers. However, users should keep in mind that the process is slightly different for removing dirt and grime than maintaining their motorhomes’ luster.

Surprisingly, the 64 oz. container is enough to cover the surface of a large camper. I even had a little bit of the product left after waxing a 38-ft. RV.

7. Collinite 925 & 920 Fiberglass Boat Wax & Cleaner

Do not let this boat wax and cleaner fool you into thinking that this combo pack is only suitable for marine vessels. It can also work wonders on fiberglass RVs.

Unlike many kinds of fiberglass wax with mixed formulas on the market, this two-piece set allows its users to use dedicated products for specific purposes. As such, RV owners, such as myself, can enjoy a more concentrated formula to clean and restore campers’ surfaces.

In my experience, it can eliminate accumulated damages from oxidation, rust, and stains. It also restores the lost color of fiberglass. It also provides extra protection against chalking, corrosion, and UV rays.

8. 3M 36113 Perfect-It Boat Wax

This boat wax, designed to restore the aesthetics of marine vessels, can also recover the lost luster of different RVs.

The pure carnauba wax containing in this product produces a high-gloss, wet finish that will make campers look like they came straight out of high-powered car washes. It also protects surfaces with exceptional durability as the applied motorhome did not acquire significant damage since this product’s initial application took place weeks ago.

It doubles as wax for gelcoat RV, and it is usable on painted surfaces. In my experience, this wax tends to apply the same level of protection to other surfaces, enhancing material durability, unlike many others.

Furthermore, this wax does not leave a residue. Cleaning the solution tends to be as straightforward as its application. So, I do not have to waste the entirety of a beautiful weekend maintaining my camper when using this product. A few hours of routine RV maintenance is sufficient when I am working with this wax.

Moreover, this product is quite reasonably priced. I did not have to spend extra cash to purchase a quart of this wax.

9. Bio-Kleen M00607 Fiberglass Cleaner

Many RV wax types could not make me say, ‘I made a worthy purchase,’until I bought this product from Bio-Kleen.

First, it has a spray-on nozzle, which makes applications reasonably easy. But it penetrates surfaces quite fast to dissolve filth buildup within seconds. I found that it can remove unclean substances like rust, corrosion, algae, and chalking.

Second, its versatility is in league with the best of its class. I used it on fiberglass, marble tiles, granite, porcelain, and different metals while producing satisfying results. I even used it on sinks, bathtubs, and toilet seats, and this wax produced a shine on those surfaces that made them look like I recently bought those items from the store.

Perhaps part of its versatility is its non-abrasive formula. This cleaner and protectant do not leave unwanted scratch marks during applications, which would otherwise be the case if I used low-quality fiberglass wax. Its non-abrasive nature is also accompanied by its biodegradable trait. Thus, I can use it near organic objects without harming Mother Nature.

10. STAR BRITE 71500 RV Wash & Wax

It is time to say goodbye to money- and time-wasting products that fail to deliver upon using this RV wash and wax from Star Brite. It has a special formula that can provide motorhomes with a clean and premium shine in a few, sufficiently simple steps.

Aside from giving my motorhome a much-needed color restoration, it also does a reasonably wonderful job in getting rid of unclean elements. It did great in removing objects like dust, mildew, mud, bug carcasses, and grease.

On the downside, this wax tends to find it difficult in removing black streaks. I had to use multiple applications to remove black stain buildup on my camper. But, the one-gallon content is still enough to cover my RV, so I did not skimp on using this wax in eliminating those pesky streaks.

The product also came diluted, which means a small amount is enough to cover a wide area. It is an economical way to keep my camper looking new without distressing over possible wastage.

It is also non-toxic and biodegradable. So, if a time comes when I need to dispose of this product, I would not find it worrisome to dump it as this formula does not harm the environment.

What To Know Before Buying RV Wax For Fiberglass

Like purchasing relatively any product on the market, you need to consider some essential factors before buying the best motorhome wax for fiberglass. Some of these elements to think about are:

• Convenience

Does the wax have a spray-on nozzle on its container? Can the solution be used with compatible machines for faster and easier waxing operations?

Think about your experience with the product before pulling money out of your wallet for your choice of wax. A high-quality RV wax for fiberglass, especially one made from a trusted manufacturer, generally provides the most conveniences.

Take note that the wax you buy should not give you a more challenging experience than necessary. A few steps should suffice to clean, restore, and protect your fiberglass RV from different hazards.

• UV Protection

While on the topic of safeguarding your fiberglass RV, perhaps one of the most hazardous elements that can bring significant harm to your camper is the sun.

The sun’s UV rays may do a lot of damage to your RV’s exterior. Overexposure from the sun’s harsh rays may cause issues like discoloration, deterioration, and fading. Failure to remedy and protect these concerns may make your camper look rundown, even if you bought the vehicle recently.

Kindly note that fiberglass is generally susceptible to UV damage. Also, this material does not have any self-restoring capabilities to remove the harm done by UV rays. So, it is best to protect your vehicle before these types of damage have the chance to rear their ugly heads. Use the right wax, and you can have peace of mind, knowing that your fiberglass RV won’t suffer the fate of losing its aesthetic appeal from the sun’s rays.

• Versatility

Get the most value out of your RV wax purchase by ensuring that the product is usable on different materials and surfaces. Although you can still gain tremendous value from a dedicated wax for fiberglass RVs, you might not want to spend additional cash in buying other products, such as cleaners and protectants, for other materials.

Search for an RV wax that you can use on your fiberglass motorhome and other surfaces. Some motorhome wax options can be used on materials like certain metals and plastics.

If you have doubts or questions about which RV wax is usable on different surfaces, don’t hesitate to look at online reviews before purchasing the item.

• Shelf Life

Many types of wax for fiberglass RVs tend to come in differently-sized containers. It is possible to purchase 16 oz. bottles for small maintenance jobs. But you can also buy large ones that may cover large 40-ft. motorhomes.

If you decide to buy the large containers, make sure that the contents do not expire soon. Some wax variants tend to leave users with a small amount after rigorous waxing sessions. That relatively small amount of wax might still be enough for weekly or bi-weekly maintenance operations for fiberglass RVs.

It will be a waste to throw out the contents of the container if it is unused. Therefore, wax with a sufficiently long shelf life is a must to avoid unnecessary wastage.

• Safety

The right wax for fiberglass campers also needs to be reasonably safe to use. Kindly note that you still need to use a relatively strong formula to ensure your fiberglass RV keeps its pristine appearance. But, the mixture should not be too harsh that it has the potential to damage skin.

Also, aim to use biodegradable variants. That way, you will not risk harming Mother Nature’s gifts during use or when you dispose of the bottle’s unused contents.

• Price

Buyers of different financial standings tend to look at the costs of their upcoming purchases. The product’s price is generally a primary determinant if the individual is going to pursue the transaction or not.

As such, ensure that the price of the fiberglass RV wax fits your spending allowance. Keep in mind that an expensive product does not always mean that it will give you the best value. On the other hand, an inexpensive variant might provide more value than its costly counterpart.

Therefore, make sure to read online reviews, such as the list of the best fiberglass RV wax options above, before making your purchase. If you do, you might have a better chance of avoiding buyer’s regret.

The Different Types of RV Wax for Fiberglass

Aside from thinking about factors, it is also essential to consider the type of RV wax for fiberglass to buy. Although different RV wax options exist on the market, it is possible to group those products into three major categories.

• Liquid RV Wax

Perhaps the most common yet most popular type of wax for fiberglass RV is the liquid model. Liquid wax tends to be in bottles, which is generally suited for applying over large surface areas, such as Class A RVs.

• Paste RV Wax

A paste wax usually requires more time and effort to apply than its liquid sibling. This variant is not as common as liquid waxes, but paste waxes might be ideal for small routine repairs and maintenance on fiberglass surfaces.

• Spray-On RV Wax

Perhaps the easiest to apply out of all three RV wax categories, the spray-on variant tends to common in relatively small to medium bottles. Thus, this option might not be ideal for covering large campers. But it can still be a good option for cleaning and maintaining small to medium RVs.

Benefits and Drawbacks of RV Wax for Fiberglass

The advantages and shortcomings of the different types of RV wax for fiberglass are generally distinct for each variant. For instance, a particular wax might be more convenient to use than another model. Still, many kinds of fiberglass RV wax share some common benefits and drawbacks.

Common Benefits of RV Wax for Fiberglass

• Usable on different materials, such as fiberglass, plastic, and painted metal
• Environment-friendly and safe to use

What Is The Best Wax To Use On A Fiberglass RV

Kindly note that the ‘best’ wax to use on a fiberglass RV tends to be unique for each vehicle owner. In other words, one person’s ‘best’ wax might not be the best for another individual.

With that said, certain fiberglass wax options exist that tend to produce better experiences than others. Aim to shop for the types of RV wax that can deliver optimal convenience, durability, and protection to your camper vehicle. Furthermore, make sure that it is at the right price to fit your current spending allowance.

Read online RV wax reviews before making your purchase. Take the time to read the feedback of other people to help you make an informed decision and avoid buyer’s regret.

Who Makes The Best Wax For Fiberglass RV

Many trustworthy brands of wax for fiberglass RV exist on the market, making it tough to select the right product. Still, some companies excel at their crafts in creating special types of wax for fiberglass campers.

One company to keep an eye on is Star Brite, a leading manufacturer of marine maintenance products. This business produces different polishes, cleaners, motor oils, and, of course, RV waxes.

So, if you are having trouble choosing which wax to buy for your fiberglass RV, a Star Brite variant might be a safe choice.

How Do I Shine My Fiberglass RV

Before answering the question, ‘how to polish RV fiberglass,’ you should take a look at the label or owner’s manual of your chosen fiberglass RV wax. Some options may have unique application instructions. Failure to follow the specifics might lead to serious and costly issues.

Now, assuming that you already purchased your preferred RV wax and read the instructions, you may have different options in applying that product.

First, you might apply the product by hand. This means that you should use a clean cloth (a microfiber fabric is ideal) to apply and spread the product to your RV.

Next, you might consider buying a dual-action buffer. This power tool might make you spend more cash than intended, but it can make waxing operations significantly faster and easier than before.

Still, keep in mind that some types of wax are not compatible with power tools. So, you should read online reviews or instructions first before purchasing to avoid costly mistakes.

Will Vinegar Remove Oxidation From Fiberglass

If you do not have access to a fiberglass RV wax, you can use vinegar and other ingredients to help restore the luster of your vehicle. Mix white vinegar with baking soda in a spray bottle. Spray the solution on your RV and let the mixture sit for a few moments. Clean it with a sponge afterward to remove any residue.

Conclusion

By now, you should have a better understanding of the best RV wax for fiberglass for your specific needs.

Remember, consider buying the right RV wax for fiberglass surfaces that can provide first-rate experience and value. The product you are going to use should give top-notch convenience and protection for your camper. Also, it should be at a price that is within your spending allowance.

If you want to go with my recommendation, consider buying the 3M 36113 boat wax. Despite the product being marketed to marine vessels, it is still more than an excellent choice for fiberglass RVs, thanks to its plethora of useful features.
