My front cap was painted and clear coated last year. Heartland helped me out with it. My rear cap was just as bad this year. There was no UV inhibitor in the gray gel coat is what I was told. I found the directions to clean and coat my rear cap on another website. I coated it with ZEP clear acrylic floor wax. Yes, floor wax. The results were nothing more than spectacular! Someone posted the directions on here recently, also. My total cost was around $25.00 and I have material left over to do about this about 20-30 more times. It's supposed to last a couple years, after which you just wash it with soap and water and wipe on a couple more coats...We'll see. They are raving about it on RVNet....Don
