My buddy had his skiff repainted there, and his nonskid started chipping 2 weeks later. I know stuff like that can happen, but I'm guessing it was bad prep. When I had my skiff painted, I took it to High and Dry Boatworks off Spruill Avenue and was very pleased with the final result. But, if you only need fiberglass and gel work, I might check out Andy Arnold. He won't give you a yacht quality finish, but his prices are tough to beat.
Here was my skiff after High and Dry painted it.
