23Bucket's comment brought something to mind that fits in nicely here, so here goes. When I paint and hit he final prep stage, which is the last cleaning before I start shooting paint, from that time forward I wear plastic gloves all the way until its ready to cut and buff. At no time after its been cleaned does anyone touch any parts that will be painted. There is one exception to this, but it only happens when there the job is temporarily sealed and sent out to an artist for very specialized work. I buy the gloves by the boxfull, I think there are 100 sets per box, at a local medical supply place, get the ones with no Talc, they're cheap insurance. Oh, and if so much as a drop of L-thinner hits them they die.
