Reply to comment by patco81 in TIL American WW2 airplanes were sent to war unpainted starting in 1943. The polished surface made the planes faster and lighter, giving more range to all planes and more cargo hold for the bombers by PatmygroinB
I learned from QI that one of the reasons most planes are light in color is that the extra pigment in the paint to make them dark would be a significant amount of weight.
