My Dart Swinger Project!
you can do it with a mig. turn it way down if yours doesn't auto adjust. have the wire feed turned up a little. need to experiment but you want to keep the nozzle moving and the wire needs to keep up. keep doing laps around the edge pulling the puddle in a little each time.
also, the nylon cup brushes on a die grinder will take the undercoating off great. but wear a mask, and eye protection. and not one of those POS paper ones, but one with real filters that can be changed.
