Ed. note: Lawrence, , it would be ideal to retain a metal finishing consultant or at least align yourself with local suppliers who can walk you through these issues, hands-on. Good luck.
Lawrence, the answer to your first questions is easy. A double rub in the solvent resistance test is the forward and back motion made with a cloth wet with the solvent specified, pressing against the painted surface.Roy Nuss
