If you’re the proud owner of an RV, then you know that keeping it in good condition is essential for enjoying your trips. One of the most important things to keep clean and polished is the fiberglass surface. There are a lot of different waxes on the market, but which one is best for your RV? In this comprehensive guide, we will discuss the pros and cons of each type of wax and help you choose the right one for your vehicle.
What Is A Fiberglass RV Wax?
A fiberglass RV wax is a specially formulated type of wax designed to protect and shine the exterior finish of recreational vehicles (RVs) made from fiberglass. This type of wax can help preserve the glossy finish of an RV’s exterior and make it easier to clean.
Fiberglass RV waxes typically contain Carnauba wax, which is known for its ability to provide a high-gloss shine. In addition to Carnauba wax, fiberglass RV waxes may also contain other ingredients such as polymers, resins, and oils.
These additional ingredients can help increase the durability of the wax and provide additional protection against UV rays, oxidation, and water spots.
Can you wax fiberglass RVs?
The answer is yes, you can wax a fiberglass RV. In fact, it’s a good idea to do so on a regular basis. Waxing will help protect the finish from dirt, grime, and UV rays. It will also make the RV look shiny and new.
There are a few things to keep in mind when waxing a fiberglass RV. First, be sure to use good-quality wax. Second, apply the wax in a thin, even layer. And third, be sure to buff the wax off with a clean, dry cloth.
Waxing an RV is a relatively easy process. Just be sure to take your time and do it right, and your RV will thank you for it.
Why do you need A FiberglassRV Wax?
If you own a Fiberglass RV, then you need to wax it. Here’s why:
To protect your investment
Just like any other vehicle, an RV needs to be properly maintained in order to keep it looking its best and preserve its value. A good coat of wax will help protect the paint and gel coat from ultraviolet rays, road salt, bugs, and other environmental hazards.
To make cleaning easier
A properly waxed RV will be much easier to clean and will resist staining from dirt and grime.
To restore shine and luster
Over time, the paint and gel coat on an RV will lose its shine and luster. A good coat of wax will help restore the original brilliance.
To Prep for Winter Storage
If you plan on storing your RV for the winter, a good coat of wax will help protect it from the elements and make it easier to clean when you take it out of storage.
There are a few different types of waxes on the market specifically for RVs, so be sure to choose one that is compatible with Fiberglass. A good quality RV wax will last for several months, so it’s not something you need to do every week. However, you should plan on waxing your RV at least once a quarter to keep it looking its best.

How To Choose The Best RV Waxes That Are Safe For Use On Fiberglass Exteriors
Differing from other products on the market, these five fiberglass waxes for RVs are the best of the best. But how do you decide which one to buy? Let’s explore some key factors that will help guide your decision so that you can choose the right wax for your RV.
Typical Wax Ingredients
The ingredients in RV waxes influence their performance as well as how eco-friendly they are.
RV waxes typically contain carnauba and other natural oils, petroleum distillates, and polymers or resins.
Waxes Made From Natural Waxes And Oils
There are a variety of natural waxes that can be used to wax your RV. The most popular is carnauba wax, which comes from the leaves of a Brazilian palm tree. It is very hard and water-repellent and is known for leaving a glossy finish on surfaces. However, it needs to be reapplied frequently in order to maintain its shine.
Other natural waxes that can be used include those that combine carnauba with beeswax or other natural oils. These products provide good shine and protection but are less durable and less resistant to dirt and grime than synthetic waxes. They also have a lower melting point, making them more susceptible to dirt accumulation in warmer climates. For this reason, they need to be reapplied every 1-3 months.
Waxes Made From Petroleum Distillates
Petroleum distillates are a common ingredient in waxes. They are derived from crude oil, making them easier to spread and smooth than most natural waxes. Petroleum distillates can leave behind a greasy residue, so you’ll need to be cautious when applying them to RVs with a gel coat or topcoat finish. Some premium RV, car, and marine waxes contain petroleum distillates, but they can also deteriorate the gel coat finish and accelerate paint oxidation over time.
Waxes Made From Polymers And Resins
Some of the latest products available are made with a combination of polymers and resins.
There are synthetic substances that work better than waxes made of natural ingredients and provide a longer-lasting protectant.
Many waxes contain extra polymers and resins that harden the wax, making it last longer and improving its shine. However, solutions made from special polymers and resins provide a duller shine than those containing natural waxes or petroleum distillates.
Wax Packaging
RVs come with three main types of waxes: liquids, pastes, and spray-on applications. Let’s take a look at the advantages and disadvantages of each type more closely.
Liquid Wax
Liquid wax is a versatile option for RV maintenance because it can be applied by hand or power, comes in various sizes, and is suitable for both frequent and occasional use. If you have a smaller RV that only needs to be waxed once or twice a year, a lower quantity may be sufficient. However, if you have a larger RV that requires more frequent waxing, you’ll want to find a liquid wax with at least one gallon of capacity.
Paste Wax
Paste waxes, like those derived from carnauba, must be applied by hand. This makes them difficult to use and time-consuming to wax your entire RV. They are less common for RV applications because of this.
Spray-On Wax
Spray waxes are a popular option for RV waxing because they are easy to apply and typically don’t require much time or effort. You can often spray them on with one hand while using the other to polish them with a polisher or hand pad. The downside is that the bottles of solution tend to be small, and the spray nozzles can lead to overspray. This can cause you to run out of wax before finishing the job on a larger RV.
If you’re looking for a wax product that will provide an all-over shine to your RV, spray-on waxes are not the best option. They’re not as economical as other products available, and we recommend buying at least one extra bottle than what you think you need in order to complete a wax job. If you’re new to using spray-on waxes, we suggest trying one out on a small spot or blemish on your RV before using it on the entire vehicle. The small bottle size makes them more effective for this type of application.
Which is best?
These are the three main types of waxes available for RVs. Each type has its own set of pros and cons that you’ll want to consider before making a purchase. When it comes to choosing the right wax for your RV, there is no one-size-fits-all solution. The best way to determine which wax is right for you is to experiment with different products and find the one that best meets your needs.
Your RV Finish
The type of finish on your RV will determine the best kind of fiberglass wax to use. Here are some basics about the most common types of RV finishes.
Fiberglass/Gelcoat
The most common type of RV finish on the market today is fiberglass/Gelcoat. The term “fiberglass” here actually refers to the type of cloth that is used as a substrate material, with resin then applied to form a hard material.
To complete the process, a gel coat is applied for extra weather resistance. These finishes are predominantly white or cream-colored, and they frequently feature a decorative decal or striping on the exterior.
RVs usually have a small amount of paint on the bottom section or to finish the decal striping. Over time, fiberglass/gel coat finishes need regular cleaning and waxing because they’ll become gradually more transparent, chalky, and uneven without it.
The best thing about this type of RV finish is that you can use any kind of car or marine wax on the bottom painted section. If you need to get rid of surface oxidation, choose an RV wax with a chemical or abrasive cleaner that removes oxidation. The simplest way is to find a product that cleans and waxes in only one application.
Corrugated Fiberglass
RVs with a corrugated fiberglass finish can be identified by their rough or ribbed texture. The smooth surface found on all other types of RVs, trailers, and toy haulers is not present here. This inexpensive Option is popular among those marketing for an RV today and usually comes in the color white with some sort of vinyl decal striping or lettering.
RVs with a rough texture can be more difficult to Wax effectively because of their finish.
On cheaper vehicles, this is used more so because they don’t last as long even when you take care of them.
Bare Or Coated Aluminum
The aluminum finish is now pretty rare, and it’s only produced by Airstream in their line of trailers. There are a few other brands that utilized this finish on RVs or trailers back when they were first made.
Although many have gone out of business or been bought by other companies, you can still find some of their models on the market.
The best way to clean an RV or trailer with a bare aluminum finish is to use a gentle abrasive polish.
However, newer RVs and trailers made from aluminum that have a clear coat applied can be taken care of in a similar way as the paint on your car.
Fully Painted
RVs with this finish type are typically painted in two stages: the first is applying a base color coat, and the second stage involves putting a clear topcoat over the initial base.
A fully painted finish is going to be the easiest to wash, wax, and detail because it has a smooth surface.
Fully painted finishes on RVs and trailers cost more upfront, but they last longer and don’t fade as quickly in direct sunlight.
Price
When looking for the wax to protect your RV, it is important to consider the price. Some waxes are more expensive than others, but it is important to remember that you get what you pay for. The most budget-friendly solutions may not be the highest quality wax products available.
It is also important to consider how much quantity you will need for a complete RV wax. A one-gallon liquid solution that can be used for multiple wash-and-wax cycles is typically more economical than a paste wax that comes in a smaller bottle. In the case of the latter, you may end up needing 2-3 bottles for a complete wax job.
Don’t just look at the advertised price when you are considering how much a product costs. The cheapest option is not always the best quality wax product.
Versatility
When looking for an RV wax, it is important to consider the surface types that it will be working on. RV waxes come in a variety of types, each designed for a specific surface. For example, waxes are designed to work on fiberglass, gel coat, metal, and aluminum surfaces.
It is also important to consider the climate you will be using the wax in and to choose one that is suited for that climate.
Some waxes have a low melting point which can be problematic in hot climates. Checking reviews from other consumers is a great way to get an idea of how a particular wax works in different environments.
Abrasiveness
When choosing an RV wax, be aware of its abrasiveness. This roughness can cause small scratches on the surface of your rig and can also lead to a hazy appearance. If you have a dark RV, experts recommend looking for a wax that is less abrasive, as the scratches will be more visible. However, any RV wax should not cause the very type of scratches and haziness it’s designed to remove.
Waxes made for RVs are usually non-abrasive because they’re designed for delicate surfaces. In contrast, if you select a wax meant for boats, make sure that it isn’t overly harsh.
If you use a wax that is meant for the same surface material as your RV’s exterior finish, in most cases this can be avoided. Also, any solution that advertises ‘non-abrasive’ qualities is likely safe to use on an RV.
Durability
When looking for wax to protect your RV, it’s important to consider how durable it is. Some waxes are only rated to last for a year before they need to be reapplied, while others may last longer. It’s important to find a wax that will meet your needs in terms of durability. Not all waxes advertise how long they will last between applications, so you may need to do some further research into user reviews to find the right product.
So, What Is The Best Wax For A Fiberglass Rv?
The best wax for a fiberglass RV is Thetford Premium RV Wax. It can be applied to a wide range of RV finishes without damaging them, and it comes in a large capacity so you can use it multiple times.
If you’re looking for a budget-friendly option, Gel-Gloss RV Wash and Wax is a great choice. It’s a two-in-one solution that cleans and waxes your RV in one easy step, and it’s biodegradable so you don’t have to worry about harming the environment when you wash it off.
Will Vinegar Reduce Oxidation From Fiberglass?
Yes, vinegar can reduce oxidation from fiberglass. Vinegar is an acidic substance that can eat away at the oxidized surface of fiberglass, revealing the shiny, non-oxidized surface beneath. To use vinegar to remove oxidation from fiberglass, simply apply it to a clean cloth and rub it onto the surface of the fiberglass. Allow the vinegar to sit on the surface for a few minutes, then wipe it away with a clean, dry cloth. You may need to repeat this process a few times to completely remove the oxidation.
Frequently Asked Questions
Even though I wish you knew everything there is to know about fiberglass wax for RV use, that’s probably not the case. Let me briefly answer some of the most commonly asked questions on this topic.
What Makes RV Wax Different Than Normal Wax?
In contrast to regular waxes, RV wax is not as harsh because RVs demand a type of wax that is less likely to harm delicate materials like fiberglass.
What Else Do I Need To Wax RV?
To do this job, you’ll need two fiberglass cloths and a ladder or pole to help you reach the upper sections of your rig.
A powered polisher may help save time if you have a larger RV and plan to apply and remove the wax yourself.
Do I Need To Prepare The Waxing Surface Before Applying it?
Yes. Applying wax to a dirty RV will cause the wax to adhere to the dirt and grime, making it more difficult to remove later.
To prepare the surface, first, wash your RV with a mild soap and rinse it completely. Then, using a clean cloth, apply to rub alcohol to any areas where stubborn residue remains (such as decals or adhesive).
Once the surface is clean and dry, you’re ready to apply the wax.
How Often Should I Wax My RV?
The frequency with which you’ll need to wax your RV will depend on a number of factors, including where you live, how often you use your RV, and what type of wax you use.
If you live in a dry climate, you may be able to get away with waxing your RV once a year. However, if you live in an area with high humidity or frequent rainstorms, you’ll need to wax your RV more often to prevent the formation of mildew and mold.
Additionally, if you use your RV frequently or leave it parked in direct sunlight for extended periods of time, you’ll need to wax it more often to protect the finish from fading.
What Type Of Wax Should I Use?
There are a number of different types of waxes on the market, each with its own advantages and disadvantages.
To choose the right wax for your RV, consider the type of finish (glossy, matte, etc.), the climate in which you live, and how often you’ll be waxing.
If you’re not sure which type of wax to use, ask an RV dealer or professional detailer for recommendations.
How Do I Apply Wax?
The specific instructions for applying wax will vary depending on the type of wax you use.
In general, however, you’ll need to apply the wax in small sections and then buff it out with a clean cloth.
To avoid streaks, be sure to work in the direction of the grain.
How Do I Remove Wax?
Again, the specific instructions for removing wax will vary depending on the type of wax you use.
In general, however, you’ll need to use a clean cloth or sponge to wipe away the wax in small sections.
To avoid streaks, be sure to work in the direction of the grain.
Once all the wax has been removed, you can buff the surface with a clean cloth to give it a shine.
Can I Use RV Wax For Other Applications?
Yes. In addition to protecting your RV’s finish, fiberglass wax can also be used to protect other surfaces, such as boats, cars, and motorcycles.
Just be sure to choose a wax that is specifically designed for the type of surface you’re trying to protect.
Conclusion
I understand that you didn’t buy an RV because you’re passionate about washing and waxing vehicles. And if that is the case, more power to you! But I’m going way out on a limb here in guessing that you probably want to spend more time adventuring or living in your RV than maintaining it.
However, you might eventually want to sell your RV and get a new one (or trade it in for a smaller model). If and when you decide to sell your car, you’ll be happy that you stuck to a regular waxing schedule so that potential buyers are always impressed!
