A buddy of mine wanted me to do a patch job on a family piece (metal bird). I have done some work for him in the past with no problem (usually yard art). This thing is kicking my ass. I've got a Mulitmatic 220. I'm alright with mig but < 1 month with tig. I made a plate out of 16 ga and have the feet down but the body is hella thin with paint. I'm all ears on what to do here. Mig is nasty (which is odd) and tig just melts the thin metal on the bird.
