I waxed and pwr buffed mine and it looked good for a while, now its back faded and getting worse. I also tried rattle can clear on it and that looked good for a few months but back to faded. The gelcoat is breaking down so nothing but a full paint coat will fix it. I bought mine used so didn't even bother trying Jayco and letting them deny me even though it was less than 2yrs old at the time. I also thought about a vinyl wrap but not sure how well that would work around the clearance light molded pockets.
