Maintaining aircraft on a carrier out at sea, I know corrosion control. If you clean/treat, then paint with single stage, seal the seams, and maintain your top, it's not going to be this extreme. If this example is the same car in 72bluNblu's signature picture, you can see a gash in the vinyl top. If you don't like vinyl tops, that's cool. They aren't the end of the world if properly repaired, installed, and maintained. Mike's Dart.... buy a car cover, enjoy your car, and don't sit on the roof. :)
