Just another suggestion. Keep your paint and your parts to be painted at the same temperature, which is to say keep them together. If you're painting bikes and you're bringing your parts in the house, bring your paint in the house too. If its a car out in the booth the night before put your paints out in the booth too. You don't want to shoot warm paint onto a cold surface anymore than you want to shoot cold paint on a warm surface. Oh, when I say paint I mean paint, catalyst, reducer, and anything else you plan to put in the cup.
