I have noticed every time washing my RV painting is coming off especially in the front fiberglass.

Repaint a old RV it's out of question
If somebody could recommend some kind of wax or shampoo to try to slow down the paint decay it will be great.

Please let me know how you do?

Another problem is the rubbers in the windshield looks good but the black stain the RV paint especially when you clean if you don't be careful you can have a lot of spots around the windshield, any suggestions to slow down this natural process.
Any products to clean those rubbers.

Appreciate your suggestions.

Nothing you can put on top is going to stop peeling paint. The damage has already been done, and the problem is on the underside of the paint film, not the top surface.

As for the black smudges from rubber moldings, you are seeing the effects of aging and UV exposure. Again, it's too late to fix what already happened, but a rubber protectant like 303 Rubber Seal Protect or Starbrite Rub Rail Restorer can slow further damage once the existing surface has been cleaned.

Thanks for your answer but the paint is not peeling off at all but in a white washing towel you can see signs of paint like water base, only in the front.

I don't know nothing about paint but for sure the paint they use on the side is different than the paint has been used on the front panel.

Thank you for your comment

Have a blessed day

Probably oxidation, if it’s paint nothing to do but let it do it’s thing or repaint.

Oxidation is common on fiberglass boats. Nothing will stop it permanently, but a good cleaning and wax will sure show it down. Go to a local marine store, or look online at West Marine, and get a cleaner and wax specifically for the job.

We get oxidation on the fiberglass roof and white streaks come down the sides. Cleaning and waxing the roof will stop it for a few months. A few people I know use mop and glow on their roof, but I have been using a polimer spray wax.

Wash and wax all

If its a bare fiberglass front cap, you can slow it down but it's gonna take some work, and regular refreshing. You'll need to remove the oxidation with a light scrub or wet sand with very fine wet-dry sandpaper, and repolish the surface. Then wax it regularly. If you have a place that sells boating supplies you can find supplies. You can search for restoring oxidized gel coat and you'll get a lot of hits from boating forums.

Another possible solution depending on the color of the fiberglass is to prep and paint with Rustoleum Topside paint. It's made for fiberglass, goes on with a brush and roller and dries surprisingly smooth. I redid my 25 year old fiberglass roof with it. It too is available at Home Depot. Not cheap but a quart goes a long way. Note: Good prep is the key.

If the oxidation isn't bad you can remove it with a scrub pad, soap and water, then polish and wax. On oxidized fiberglass side walls some people use a water based urethane or acrylic wax as a makeshift clearcoat. One brand is Zep and I believe its available at Home depot. I'm not a fan of the treatment because it will yellow. It's not designed as an outdoor finish, it's basically a floor wax, but others swear by it. If it goes back you'll need to strip it with can be a nasty project.
