Most all new cars use base coat ,clear coat. That is why you see cars running around with what looks like peeling skin on their roofs and trunk lids. Crappy clear coat. A lot of the new candy colors require a certain color of base,depending on what shade you want. And some require what color of primer you use under that. It is really a good system for show cars and such. I'veainted a lot of bikes, and most of my candy colors and base coats were water born paints. Yes, water born. I use Auto Air paints when I do custom art work on tanks and such. Much easier to work with . And a really good selection of candy colors. With a silver base , you can use just about any candy color you want.
