Painting Fiberglass Camper Shells: A Creative Diy Adventure

Painting a fiberglass camper shell is a great way to restore its appearance and protect it from the elements. Fiberglass is a durable material that can last for years with proper care, but it may require repainting every few years as it fades. Before painting, it is important to thoroughly clean the surface and remove any dirt, grease, or wax. This step is crucial as it ensures that the paint adheres properly and prevents imperfections in the final finish. When it comes to the type of paint, options such as epoxy primer, polyurethane, and acrylic enamel are recommended for their durability and ability to withstand the sun's UV rays. It is also essential to consider the application method, as some paints may require a sprayer or roller for best results. Additionally, multiple light coats of paint are generally preferable to a single heavy coat to avoid running and ensure a smooth finish.

Painting a fiberglass camper shell vs. the surface of a car

Painting a fiberglass camper shell is different from painting the surface of a car. While the preparation before painting is important for both, fiberglass does not react like metal. Fiberglass is light and durable and can last for years if proper care is taken. It will fade over time, but it can be repainted.

Painting a Fiberglass Camper Shell

Firstly, wash the camper shell with car wash soap to remove any dirt or buildup. Once it's dry, use a lint-free towel and wax and grease remover to wipe down the entire surface of the camper. This will remove all oils from the surface. Then, use 120-grit sandpaper on a long sanding block to sand the entire surface of the camper shell until the fiberglass is dull. Remember to use a small rubber sanding block for hard-to-reach places. After sanding, wipe the entire camper shell again with wax and grease remover to get rid of dust and any oil left behind from your skin. These small oil spots can cause fisheyes in the finished paint.

Next, spray epoxy or eurathane primer on the surface of the camper shell, applying three light, even coats. Allow each coat to dry thoroughly. Lightly sand the primer with 300-grit sandpaper and a long sanding block. Sand lightly, just enough to get through the surface of the primer without reaching the fiberglass. This will leave a smooth, primed surface for the paint.

Now, you can paint the fiberglass camper shell with four coats of automotive paint. Apply light, even coats, overlapping each coat as you spray. Spray lightly so the paint doesn't build up and run. Make sure each coat dries completely before applying the next one. Finally, add three coats of automotive clear to the camper shell to protect the paint from UV rays, small scratches, and chips. Allow each coat to dry.

Painting the Surface of a Car

When it comes to painting the surface of a car, the process begins with repairing damaged spots and stripping the existing finish. Start by pulling out large dents using a dent repair kit and a hot glue gun. Fill in gouges, dings, and depressions with body filler putty, and wait for it to harden. Sand the edges around the hardened filler to smooth it out, using 150-180-grit sandpaper in different directions.

To strip the existing finish, use a sanding block or an electric orbital sander to remove paint from large areas. Run the sander in a circular motion over each area, applying consistent pressure to ensure even paint removal. Continue sanding until there's no visible gloss or seams remaining. After sanding, wipe the painting area with a clean, wet rag to remove debris.

The next step is priming the body for new paint. Mask any parts of the vehicle you don't want to get primer on, and apply a base coat of automotive primer using a paint sprayer. Hold the nozzle of the sprayer 6-8 inches away from the surface and move it back and forth slowly, aiming for even coverage. Wait 20-60 minutes for the initial coat to dry, and then block-sand the base coat to smooth out any inconsistencies. Apply one or two more coats of primer, allowing each coat to dry before sanding and starting the next one.

Comparison

The key differences between painting a fiberglass camper shell and the surface of a car lie in the materials being painted and the specific products used. Fiberglass requires different types of primer and paint compared to metal car surfaces. Additionally, the steps involved in preparing the surfaces also differ, with cars requiring more extensive dent repair and paint removal.

Remember to always work in a well-ventilated area and follow the safety instructions on all products used. With these steps, you can effectively seal loose fiberglass on the inside of your camper shell, creating a durable and comfortable space for your camping adventures.

How to restore a faded fiberglass camper shell

A fiberglass camper shell is a durable and lightweight option for camping. However, over time, it can become dull and faded due to oxidation. Oxidation occurs when the gel coat covering the camper shell reacts with oxygen in the air and can be accelerated by factors such as excessive heat, direct sunlight, air pollutants, and water. While regular waxing can slow down this process, it is not a permanent solution as the wax decays over time. Here is a detailed guide on how to restore a faded fiberglass camper shell:

Step 1: Wash the Camper Shell

Start by thoroughly washing the camper shell with car wash soap to remove any dirt, build-up, or air pollutants. Once the shell is clean, allow it to dry completely before moving on to the next step.

Step 2: Sand the Camper Shell

Use 120-grit sandpaper on a long sanding block to sand the entire surface of the camper shell. For hard-to-reach areas, you can use a small rubber sanding block. Continue sanding until the fiberglass surface becomes dull. This process helps create a rough surface for the paint to adhere to.

Step 3: Remove Oil and Dust

After sanding, use a wax and grease remover to wipe down the entire surface of the camper shell. This step is crucial as it removes any oils or dust that may cause issues with the paint finish.

Step 4: Apply Primer

Spray a light and even coat of epoxy or urethane primer onto the surface of the camper shell. Be sure to follow the instructions on the primer and allow each coat to dry thoroughly before applying the next coat.

Step 5: Lightly Sand the Primer

Lightly sand the primed surface using 300-grit sandpaper and a long sanding block. Sand lightly, just enough to smooth out the surface without sanding all the way through to the fiberglass.

Step 6: Paint the Camper Shell

Paint the fiberglass camper shell with automotive paint, applying four light and even coats. Use overlapping spray patterns and avoid building up the paint to prevent running. Allow each coat to dry completely before applying the next.

Step 7: Add a Clear Coat

To protect the paint job, add three coats of automotive clear to the camper shell. This will shield the paint from UV rays, scratches, and chips. Be sure to let each coat dry completely.

Alternative Method: Hand or Power Buffing

If your camper shell has minimal oxidation, you can try hand buffing or power buffing instead of the above steps. For hand buffing, apply a fiberglass restorer to a non-scratch kitchen sponge and buff the surface of the RV by hand. Then, wipe off the product with a clean rag. For power buffing, use an electrical power buffer to remove the oxidation. This method is quicker and less strenuous on your arms.

Wet Sanding as a Last Resort

If the oxidation is severe and the above methods do not provide the desired results, consider wet sanding as a last resort. Wet sanding involves using sandpaper to remove the outer layer of the wax coating that has been damaged by oxidation. However, this method is time-consuming and requires caution to avoid damaging the fiberglass outer layer.
