The only problem with MIG is using the wrong wire for the job. I would weld that with .023 with an ER70S2 or 3 wire. Not always available since most welding is structural and most suppliers only stock 'S6 or 7. The S2 is made for doing sheetmetal. It grinds easy and has less shear strength than the others. Perfect for body panels. Zap it in 1 spot at a time overlapped so it looks like a tig weld and forget it for life. It works for me.
