The "no dark color guys" probably used a general purpose resin, what I call a "camper shell" quality. Cheap, but not the best for a car - especially a dark one. Bottom line, if the correct resin is used, the car is "cured" when you get it, and you can paint it any color you like
You know deep in your heart that the cheaper bodies used the cheap resin ... that's one way they can be sold cheap ...
