I have a friend who was a professional body man before he retired, and he usually does my welding for me. When he is replacing a panel he usually crimps both sides with an air crimper, so that he creates a smooth lap joint, punches small holes in the crimp on the outside piece and then welds those shut. As a rule, he doesn't try to make a continuous bead on the joint. He has done some really nice body work for me, and I think he does know what he is doing. I have a MIG welder which seems to do a nice job on sheet metal. Allen
