Dear Montana wizards,
I have a 2020 Montana 3780RL bought from a Canadian dealer in 2023. The original owner of the fifth wheel lived in AZ. While the Montana now lives in a milder and moister climate than Arizona, I believe it must have taken a lot of sun early in its life. Reportedly it was stored for nearly two years during the CV-19 period, but I have no idea whether that was outdoors or in. The Montana was in excellent shape when I bought it in the spring two years ago.

The issue: Up at the top of the cap, between the front roof seam and the full, rounded nose of the cap, is the area that could be likened to the 'forehead' of front 'face' of the fifth wheel. In this area, across the horizontal width of the RV cap, the finish on the gel coat has blistered and is very fragile. Even lightly brushing it takes the coating off right down to the dark base material underneath. I'm scared to mess with it! But I want to protect the RV surface and stop further decay here.

Solutions? I'm wondering what the best way is to treat this area, halt further deterioration of the surface, and seal the surrounding surface to keep the problem right where it is. I have no idea what kind of paint, or sealant, or other product to use to accomplish this?

Has anyone dealt with this issue? Thank you!
 
We live in Florida full time and have the same problem with our 2014. The sun has burned the clear coat. Ether you can have the cap sanded and sprayed clear again or make a cap bra from sunbrella or some other material or just keep spraying with 303 and deal with it.

Thanks for your suggestions. I hadn't thought of using 303 on that surface.
