Can You Use Ceramic Coating on RV Fiberglass?

Protecting the fiberglass exterior of your RV with a ceramic coating is a great idea. It provides UV protection and a durable finish that will last for years. You can also use a ceramic coating to repair damage on the surface of your RV’s body, such as dents or cracks. The application process isn’t too complicated and should only take an afternoon or two, depending on your vehicle size.

Ceramic Coating Can Be Used on Fiberglass

Ceramic coating can be used on fiberglass, which is a great way to protect the surface of your car. It will help you to keep your car looking new for years.

Applying a ceramic coating to fiberglass can be done in a few different ways, but the most common method is using a spray or roll-on application.

Ceramic coating for RVs can be applied by either spraying or rolling on the coating, although some people find that spraying is the easiest method. The spray method involves spraying the coating onto the surface where you want it to go and allowing it to dry before doing any more work. You may need to wait up to one hour before moving on to another step.

Rolling on ceramic coating can take more time than spraying it, but it also gives you more control over how much gets applied at once. This method works best if you want uniform coverage over an entire surface or a large area of fiberglass.

Why Is It Important to Ceramic Coat RV Fiberglass?

It’s important to ceramic coat RV fiberglass because it protects the surface of your vehicle from oxidation and helps prevent scratches and dings. Ceramic coating provides a protective shell that keeps moisture, dirt, and other contaminants from penetrating the fiberglass. This helps protect your vehicle’s paint job against damage. It also helps keep your RV looking new for longer, which means you can enjoy its beauty for more years.

Aside from protecting your vehicle’s paint job from damage, the ceramic coating has the following advantages:

  • It provides a glossy shine that makes you look good when you drive around town
  • It makes cleaning easier by repelling dirt and grime, so you don’t have to clean as often
  • It helps prevent rusting on metal parts such as wheels and frames by forming a barrier and water or moisture in the air

How to Prepare the RV for Ceramic Coating Application

Before you can start applying the ceramic coating, you need to prepare your RV. This will ensure that the surface is ready for a smooth application and long-lasting protection. First, prep the surface with an appropriate cleaner. Do not use harsh solvents or abrasives since they can damage the paint job or cause cracks in the fiberglass shell. Instead, use a mild soap solution or water and a soft cloth to gently remove any dirt from the surface.

When your RV is clean and dry, use a tack cloth to remove any remaining dirt particles that may have gotten onto your vehicle during this process. Remove any stickers or decals from windows before applying the ceramic coating. Otherwise, if they get damaged during the application process, it may be difficult to clean them off later.

Finally, ensure that there are no large pieces of debris left behind from previous repairs before starting the application process. You don’t want anything blocking your view while working, so take care of all this beforehand by removing anything that might get stuck in the paint job afterward!

Applying the Ceramic Coating on Fiberglass RV Body

When applying the ceramic coating, following the manufacturer’s instructions and using the recommended tools is important. If you do this, you’ll have a much better chance of getting the desired outcome. The following general guidelines can help you get started:

  • Apply the ceramic coating in the direction of the grain on your fiberglass RV body. This will ensure that when water hits it after installation, it runs off rather than soaking into any cracks or crevices between layers of paint or fiberglass.
  • The best method is to apply a high-quality ceramic coating that will last for years. The coating will protect your vehicle from UV rays, moisture, and other environmental factors. It will also give your vehicle an added layer of protection from scratches and dents caused by rocks or other objects hitting your vehicle’s body.
  • Apply thin layers of ceramics coating so that each layer has time to dry completely before adding another layer on top. This will prevent bubbling or sagging at each application spot where two different colors meet simultaneously while drying simultaneously.

Curing the RV Body Coated with Ceramic Coating

You can now enjoy your RV, which is ready for use. There are a few things to keep in mind after the coating has been cured:

  • Let the ceramic coating dry for at least 24 hours. If you need to use your RV during that time, cover it with plastic so that no moisture can get in and ruin the seal on the paint job.
  • After 24 hours, wash loose debris or dust particles with soap and water. You may also want to use mild cleaning solutions if you want something more thorough than just soap and water.


Ceramic coating is an amazing product that can drastically improve the appearance and feel of your RV. It is also easy to apply to your fiberglass body if you follow the instructions. Ceramic coatings can be used to improve the durability and performance of fiberglass when properly applied. They can protect your fiberglass from deterioration and keep its beauty for many years.
