Mossy mess on faded paint

@ WWRandall and Dalmationlovers, I used a combination of your ideas . . . after a spray wash at the local car wash to remove the heavy dirt and a hand wash and it worked great.

Roof top . . a bit more work.

Window seals are a bit harder looking on the windshield than perferd, but no cracking just have a very dull flat appearance. A short time ago, finished the first coat of wax/cleaner on the front, back and sides. Looking really good again, surprised myself. Not sure what to do on the roof if is it paint or a gel coat on the fiberglass? :?

I see suggestions on other forums saying it is paint and other say it is gel coat. :@

Powerwashers can drive water under cracks in the paint and cause it to flake off - I'd use something a little more gentle at first until you know what you have to work with, just to be on the safe side. It's not that much work to get it off by hand...

If you use a power washer, be careful. A neighbor used his washer that he uses to clear the moss off the driveway. He had an older Class A, never thought to check what pressure it was at, and the 3000 psi jet actually punched a hole in the fiberglass back wall of the rig!

Just a thought but you could use a power washer to get the worst off then follow with the soft scrub to get the rest of it off followed by polishing

~ Excellent ideas folks :)(had not thought of the Softscrub which is odd as I have used it to clean the white side wall lettering in the past. Getting older I suppose). :h
Time to do a store run, picking the rig up Saturday.

You may even try some soft scrub and a light sponge. It takes time, but will come off. You will have pitting, but use a rubbing compound and then polish.

I've had reasonably good experience with bleach and water with a scrub brush (small circles with light pressure - patience will be rewarded!), followed up with a careful application of polishing compound (follow the directions and you'll be fine.) There may well be some pitting as the 'roots' of the moss will have anchored in the surface of the fiberglass over time, but the paint should clean up nicely. Seals, on the other hand, may have hardened or cracked due to their experience, but the same cleaning should at least remove the detritus and allow you to see what you're left with. I don't know of anything that will 'renew' aged rubber seals other than replacement...
