Rust repair...

I bought a little MIG welder - figured if I have a track car I'm bound to be needing to fabricate and repair things all the time so it was worth while to get a MIG. I started cutting out the few spots of rust in the shell and replacing it with fresh metal donated from a Magna door skin I salvaged from the scrap bin at a local panel beaters! It was working out pretty good, I could have been a panel beater in a previous life!?
