nolimitazns

sup guys my friend has a 90 Acura Legend n he tinted his rear tails red on top and light smoke for the reverse lights. It looks bad ass. I was thinking it might look pretty nice on a 03 TLS. The tint is removable and goes right on the lens so I was thinking tinting the reverse light all the way across the top of the rear tails would look pimp. Any ideas? I was also wondering how hard it would be to spray my engine cover and battery cover. The duplicolor sprays are about 3 bucks a bottle. Does anyone have instructions to do it? Priming it etc? Thanks
