Im going to get the hood of my truck painted. The rest of the truck is good, but the hood is terrible. Anyway, I noticed yesterday that the top of the cab is also in bad condition. Not as bad as the hood, but not great. Anyway, here is my question. You cant see the top of the cab so if I didnt paint it, no one would notice. So, if I were to just get a can of clear coat and spray that on, would it keep it from getting worse and stop any rust that might some day appear?
