The difference between black and white is that you can put your hand on a white car that has been sitting in the sun, you cannot on a black car. Amazing how hot black will get.
I was doing some caulking on our Dynasty roof and we basically have a white coating on most of the fiberglass roof. The black color comes up on top of the roof about 3 ft. over the driver's area. If the coach has been sitting in the sun for a while, I cannot touch that black area to wash it, I have to stay in the white coated area and reach over.
