Thought I'd share my latest project. I'm going to try to do the DIY repair on my peeling clear coat. Lots have been said on this subject, most geared toward sand, prime, basecoat, and clearcoat. I've got an unaffordable estimate of $3000 to do just that.
This morning I got up, and thoroughly cleaned the painted fiberglass roof. In my opinion, it cleaned up very well, with car wash and soft brush first, and secondly with magic eraser. The clear coat on the roof is completely gone, but the paint appears to be in good condition. I plan to use Wet Look Zep on the surface of the roof. I've used Zep on another motorhome, and am totally happy with the results.
The radius where the clear coat is peeling will be a bit more challenging. I'm planning to use a plastic razor blade to scape the peeling line to a hard edge. Wet sand 1500 grit on remaining clearcoat, and very lightly sand the exposed basecoat. I'm not going to try and feather the peeling edge, and rather hope I've got a good, well adhered hard edge. 3 coats of raddle can 2K clear in the radius area only, will hopefully do the trick.
There is evidence that this is not the first repair to the radius area of this coach. There is a distinct line where a previous repair was done. Just got this coach last year, so don't know how long it lasted.
Last part of this project will be detailing the paint.
