1. I want to get a black set for my black steelies (winter tires) and I would like to use the silver ones that I currently have for my summer wheels.

2. The paint would likely come off at the mere sight of a socket.......if not, it would definitely chip off once the wheel is torqued. I don't mean to this response to come off sounding like an ass, but painting lugs (DIY).....well, it just doesn't work very well.
