I am painting my 64B. I want to stay with original colour. Painter wants to use 2 stage water borne, and clear coat. He says Dupont does not have a code for Iris blue in this paint, and wants to match to a car panel. We could get a factory code for Iris blue in acrylic enamel, and be sure of the colour. Which paint system do you suggest, and if base/clear, can I find a Dupont code for Iris blue? THANKS
