any1 remember the matchbox cars that you could put in hot and cold water and it would change colour??? (you can get the idea where im going here...)
CAM COVER PAINT!!!
at a show you have say a green cover cause its cold, start her up and yellow she goes!!!
since really this i jus an idea im sure it could get shot down rather quickly eg: availability of paint, cost, lifetime etc...
so what do you think??
