I would like to attempt to brighten the engine compartment. The problem is the engine and all of the rest of the goods are there in the way. I decided to use an airbrush. I wanted to use a urethane base the same color as the car but am confused as to what clear to put over it. I would prefer to use a one part clear just for ease of use. Can a laquer clear be put over a urethane base color???????????
