20 years and 3 gliders ago, I needed a Schreder type aluminum trailer sanded & repainted. I took it to a guy who built racing stock cars in a shop next to his house. 1 week, $1000 cash green money, no questions & no paperwork later it came back looking great. Last time I saw it (2 years ago) it still looked good. Sorry about the ozone layer . . .
