i used to be a NAPA outside salesman. at that time we would set up auto body shops with a FREE paint mixing system. and then they would BUY ALL THE PAINT PRODUCTS that went with that paint. when i was working there ACRYLIC ENAMEL was the hot product. now its urethanes and in calif water base auto paint. check with NAPA, DUPONT, SIIKENS, BASF & HOK.
