I have a stock 74 Duster grille that has a lot of paint peeling and fading. I'd like to take it apart and paint the main grille section with the factory finish and color, or relatively close to it. This is a driver, not a show car so it doesn't have to be a prize winning paint job, but it does need to look decent and be durable as the grille gets a lot of abuse while driving. Are there any good spray can products out there that are adequate? What's the best primer or adhesion promoter to use on plastic?
