I hate using the stuff myself. Between the cleaning, tinning, leadwork, filing, sanding and killer to keep the paint on it is just a pain. I have done lead a few times and only had paint problems on one. That was due to the owner wanting to take it for a "test" drive while still in primer, in the rain. Tried to tell him about primer being hydroscopic BUT he decided He was paying the bill and could do what he wanted. Had him sign a waiver and go on his way. Took about a year for the lead to release it's grip. He came in complaining so I showed him the waiver and the door.
