I usually use a piece of rag or even paper towel in the gears to lock it up. Le Sabotage (throwing a boot into the machinery). I did a small amount of reading on the subject of paint color and heat dispersion and came up with a conclusion that color had little or no effect, so a white engine and a black engine would be basically the same. I was attempting to accomplish a flourescent green glow from behind the grille of a 63 Cadillac in 1985 without running afoul of the law, as my first attempt using two light boxes and colored filter lens was perfect in effect but illegal in practice. But a white to amber light was allowed on the front of a vehicle, so if it then was projected onto a flourecent green paint on the radiator then I thought I might have a legal standing but the police had a different interpretation, so it all went back to flat black. Just an idea a few years ahead of its time.
