Check with Fountain RV in Lakeland, FL. They have a full service paint shop.
FWIW, I spoke to you a couple of days ago at Ocean Lakes admiring how good your Adventurer looks. While your gel coat has faded, the rest of your rig looks really nice. We had our 2002 Journey painted by Commercial Refinishers in Durham, NC in 2010. It was a 36' coach. They charged me $13,500 for decal removal, surface prep and priming, 5 base colors in the scheme I selected, and four coats of clear...Dupont Chroma Premier paint. In order to save some money, I did not have them paint the sides of the slide rooms since those areas looked new. I also kept enough white in my new color scheme so all my awning arms and other exterior hardware did not have to be repainted to match a totally different color scheme. The coach turned out wonderful.
