Hello, all-
...I'm new, have looked through the posts but not found what I was looking for.
...I have a 1982 Honda Silverwing. The gas tank is dented and scabby, and the saddlebags came from another bike and thus are another color, not just a different fade of the original. I've decided to repaint the entire bike, which means fairing, tank, both fenders, both side panels, two saddlebags and a trunk.
...Those things are metal, fiberglass and plastic.
...Will one primer, paint and clearcoat work for all of them?

ps I plan to use rattlecan because I have lots of curved surfaces to paint and not much actual surface... a quart would probably coat the bike about nine times.

Thank you for the advice.
