Problem is buying the paint would make them pretty expensive. I made John's using the base/clear left over from the car. 1/2 pint of ChromaBase is about $35. It takes about an hour to make one (or two at a time for that matter). I doubt people would want to pay close to $100 for something like this. I could make 5 or 6 at a time for basically the same total cost (like $120 for 6) but 1 at a time is pretty pricey. I could make them out of vinyl for a lot less but finding the Mopar colors is difficult. Plum Crazy is available in vinyl, so is SubLime (a non-metallic version) but not much else other than black, white, and red. Nothing close to EB5, EB3, or any of the metallic greens.
