My understanding of candy painting is that you spray down a base metalic color and then a translucent color ala clearcoat with pigment. Are there any colored clrearcoats available in a spray can or do I have to purchase automotive paint and use an airbrush for this? I know it would probably look better, but I dont wanna botch this up having never used an airbrush before, not am I trying to break the bank with high end auto paint. Yes I've googled, but no such luck on the cans.
