A faded fiberglass RV can look tired fast. Chalky white film, dull panels, and lost reflection are all signs of oxidation on the gel coat.
In the video at the end of this post, the team from RV Cleaning Academy shares a simple system that shows how to remove it, restore real shine, and keep it that way with basic care.
Understanding RV oxidation
Oxidation on a gel coat shows up as a dull, chalky surface that no longer reflects. It wipes off on towels and robs color depth. This process brings back the original gloss and holds up if it is protected and maintained.
It works on old, faded fiberglass and on neglected panels. The steps are simple, so beginners and pros can follow along and get consistent results.
Tools and materials you’ll need
- Brushes, buckets, and dish soap for washing
- Painter’s tape for rubber, plastic, and window edges
- Microfiber towels for wipe downs
- Meguiar’s 1-Step compound for cutting oxidation
- Orange polishing pads for paint correction; plan on 20 to 30 pads for a full RV
- A 6-inch polishing machine with variable speed
- Collinite paste wax to protect the gel coat
- 303 Protectant for decals, rubber, and plastic
Prep the tools
- Use a soft brush, two buckets, and mild dish soap.
- Have painter’s tape ready to border seals, windows, and skirts.
- Fit the 6-inch polisher with orange pads, use Meguiar’s 1-Step compound, then finish with Collinite wax on gel coat and 303 on decals.
Step 1: Surface cleaning
Rinse the RV well, scrub with soapy water, then rinse again until the water runs clear. Let the surface dry fully before taping or polishing. Air dry or gently towel dry to prevent water spots.
Step 2: Taping off protected areas
Tape rubber weather strips, plastic guards, window seals, decals, and skirts. Clean tape lines help avoid stains and save time later. Focus on windows and seals, decals, door handles, steps, and any exposed rubber or plastic.
Step 3: Applying the compound with a polisher
Break the RV into zones. Tackle a few panels per session to avoid fatigue and keep quality high.
Attach an orange pad, add a few small dabs of Meguiar’s 1-Step compound, and start on a low setting. Work in small squares, not the whole side. Wipe the haze with a clean microfiber cloth. If a spot looks cloudy, repeat a couple of passes and blend the edges.
Change pads often once they load up. Dirty pads cut poorly and smear. Plan on a fresh pad every few sections for a full RV.
For tight spots, put compound on a microfiber cloth and rub by hand with firm pressure. Wipe clean to match the machine finish.
The difference is clear. Untouched panels look flat and gray, while polished panels reflect like glass. Keep moving panel by panel. Side by side, the restored gel coat shows a clear reflection, richer color, and a smooth, clean feel.
Step 4: Protecting the restored gel coat
After compounding, seal the finish. Apply Collinite paste wax to the gel coat. Use 303 Protectant on decals and plastic. Avoid getting paste wax on the decals.
Peel the tape, inspect edges, and spot polish or rewax any missed areas.
Wash often and reapply wax on a regular schedule. A clean, waxed surface resists oxidation longer.
The cost and value of RV restoration
A full oxidation removal job can run about $2,500, which reflects the time and labor. DIY saves money and teaches a repeatable process. The same method works for boats, RVs, and even cars.
A bright, glossy gel coat changes how an RV looks and sells. Follow the steps, work in sections, protect the finish, and keep it clean.

Take your time. Do not push on the buffer. That will destroy the pad in short order and may even buff through the clearcoat.
Let the buffer do it’s thing and keep it moving!
Do a 2X2 area at a time. After you get a large area done, quickly go over the entire area again with a blue pad.
Wash the entire surface before waxing to remove any left over compound.
I used to do used car reconditioning in my prior life. It is not hard, but does take time.
If there is substantial oxidation, a wool pad will work far faster than the foam pads and will also last longer. Probably best to then take a next step with a foam pad using a less aggressive polish before waxing.
