I know this may sound stupid, but I always wondered. When you are totally repainting a car, and your car is a light colour like silver, is it cheaper to paint to a dark colour like black and more expensive to paint to a light colour light alpine white? I ask because, with a dark colour you would not need to prime down as much since it is going darker. With white, you would need to make sure the silver will not come through or am I just an idiot? Sorry I have no clue when it comes to paint.
