So I bought a truck cap, and of course it doesn't match my truck, and the clear coat is peeling to make it extra special. How to I cheaply get passible paint on this thing? It barely has to be passible, if I can brush/roller it on even better. Would I be able to get away with knocking down the loose clear with a sander, scuffing the rest for adhesion, wipe down, and then???? Another gelcoat? Something else?
