I was recenly at a car show and a guy who works for mopaints (they destribute dyes to yearone) told me to clean them with simply green and a nylon brush not to rough of a brush cause like our good friend 4 cruzin pointed out you dont want to damage them :tongue: ! so I bought 4 cans off of him done what he said and they turned out great!!! I used some dawn and a rag first to get all the dirt off then used simply green and a course scrub brush!! good luck!! :beer:
