When talking about vehicle waxes in general, you can get either a liquid or a paste. The former option is great if you’re trying to save time. However, pastes can deliver much better protection for your RV, meaning that you don’t have to wax as often.

Collinite is one of the best RV waxes for fiberglass because you can keep your vehicle shiny and preserved much more efficiently. While the application process can be a little more intensive, it’s worth the extra effort.

High Gloss Finish
One of the primary benefits of using a paste is that you can typically get a much better shine from it. While spray and liquid waxes are convenient and efficient, they leave a thinner film that can come off while you’re on the road.

By using a heavy-duty paste, you’ll be amazed at how well it holds a glossy finish. We highly recommend using a mechanical buffer (unless you want to kill your arms), which will make the shine even more captivating.

Superior Protection
Having a shiny RV is only one reason to wax it. Fortunately, this process is both practical and aesthetically pleasing. Because Collinite is a paste, you will get better protection from all of the elements, including dirt, rain, bugs, and UV damage. 

  • WHAT WE LIKE
  • WHAT WE DON’T LIKE
  • PROS/CONS OVERVIEW

You don’t usually find wax pastes suited for RVs. However, this substance is a lot better at rejuvenating and protecting your motorhome, making it a smart buy. You can expect this material to last a lot longer than other options.

Features

  • Easy to use
  • Removes Oxidation Damage
  • Restores Color and Shine
  • Quality protection for your RV

For the most part, RV waxes are meant to provide a layer of protection, as well as deliver a pristine shine. Usually, they don’t repair the damage or restore the fiberglass surface.

Fortunately, if your motorhome does need a little extra TLC, this product from Meguiar’s is here to help. You can reverse sun and rust damage to your RV, helping to restore it to its former glory.

Removes Oxidation Damage

Generally speaking, if your fiberglass is fading, cracking, or rusting, you need to get it replaced. However, as long as the damage isn’t too severe, you can restore most of it with this wax. Save money and keep your motorhome in decent condition for longer.

Restores Color and Shine

UV damage not only weakens the fiberglass, but it makes the color fade. Thanks to the oils in this wax, the original color will brighten once you apply it.

  • WHAT WE LIKE
  • WHAT WE DON’T LIKE
  • PROS/CONS OVERVIEW

All too often, it’s easy to neglect cleaning and waxing your motorhome during the off-season. If you come back to a slightly damaged fiberglass exterior, this product can help you recover quickly.

When comparing the best RV wax for fiberglass, you’ll come across Meguiar’s a lot. This brand is one of the top in the industry, thanks to its superior performance and protection. Let’s see how this version stacks up against the others we’ve seen.

One-Step Application

Convenience is a powerful motivator when choosing the right product. If you like the idea of spending a lot less time waxing your RV (without sacrificing protection), you’ll appreciate the simplicity of this formula. One step and you’re good to go.

Marine-Grade Protection

Boats take a lot more damage than regular motorhomes. If this wax can stand up to constant saltwater conditions, it can protect your RV better than most.

  • WHAT WE LIKE
  • WHAT WE DON’T LIKE
  • PROS/CONS OVERVIEW

Although there’s nothing wrong with spending a day waxing your RV, we recognize that most RVers don’t have that kind of passion. I like the fact that you can apply and wipe off this wax much faster than most other products.

If you’ve ever waxed a car before, then you’re probably familiar with the brand Turtle Wax. Technically speaking, this product isn’t designed for RVs, but it is one of the better car waxes on the market, meaning that it should suffice for most motorhomes.

Spray Bottle Application

Much like the Meguiar’s formula above, you can be done with waxing your motorhome in much less time. Also, the fact that this product comes in a spray bottle means that you can get started immediately (provided that you have a buffer).

Versatile Wax Formula

As you’ll notice, this wax is designed for cars and trucks, not necessarily RVs. Thankfully, the protection is versatile enough to cover all vehicles well, so feel free to add gloss and protection to everything you own.

Features

As we’ve seen so far, most of these waxes are relatively small. In many cases, you’ll have to buy multiple products to ensure that you can cover your RV in one pass. Fortunately, this option from 303 products is large enough to protect your motorhome by itself.

High-Quality UV Protection

Although this protectant isn’t as flashy as some of the other brands out there, it gets the job done. The primary purpose of this wax is to keep sunlight from damaging and eroding your fiberglass, and it succeeds in spades.

Rinse-Free Formula

If you want to save time on waxing your RV, you can avoid rinsing and drying off. Simply apply the wax with a mechanical buffer, and you’re ready to hit the road.

  • WHAT WE LIKE
  • WHAT WE DON’T LIKE
  • PROS/CONS OVERVIEW

Since this product comes in a gallon jug, you don’t have to buy multiple units to cover your RV. I also appreciate that it’s focused on UV damage since that will be much more of a problem than dirt or grime.

BUYER'S GUIDE

What is the best wax for fiberglass RV?

As we’ve mentioned, our top pick is the Collinite Paste. We prefer this wax because it will protect your RV much longer than the competition.

How do you clean a fiberglass RV?

Here are a few tips to make the waxing process go a lot smoother and faster.

Clean First: the wax will adhere better if the surface is thoroughly clean.

Dry Thoroughly: Water and wax don’t mix - dry the fiberglass well before applying a new coat.

Use a Mechanical Buffer: regardless of the type you use, a mechanized buffer will make the work a lot easier.

How do I protect my fiberglass RV?

When it comes to keeping your motorhome in pristine condition, you need to do three things.

First, keep it out of direct sunlight as much as possible.

Second, clean it regularly. Wipe down any dirt or stains immediately.

Finally, wax it after each cleaning. The best RV wax for fiberglass will keep the elements from damaging your mobile home.

Can you use car wax on fiberglass?

Technically speaking, all waxes are suitable for fiberglass. However, using a material designed for fiberglass specifically will always be better than a generic version.

How often should you wax a fiberglass RV?

The answer to this question depends on the wax you use. A paste like Collinite will last months (or a full year). Spray-on waxes tend to wear off after a couple of months.

Also, it depends on how long your RV is out in the elements. If it sits around for most of the year under cover, you don’t need to wax as often.

CONCLUSION

If you want the best protection for your motorhome, we highly recommend the Collinite Paste. This product is ideally suited for keeping your RV in prime condition for months and years to come.

Although it does take longer to apply, the results are spectacular. Also, since you don’t have to use it as often, you will probably break even regarding time and energy spent.
