A: The color is a special oven-bake paint made for die-cast models -- it would not be usable for an actual car because of the high temperature that is needed to cure the paint. Also, it is from an industrial supplier that does not sell it in small quantities and does not have color codes that correspond with manufacturers of retail paint. It would be best to take our model to an auto paint supplier and have them mix a color to match it.
