I did buy one of those "flanger" air tools. One side puts a flange on the panel, and the opposite side of the tools head punches a small hole in the sheet-metal so you can do a rosette (spot) weld. Harbor Freight - $30-$40.
That reminds me, I need to buy some of that spray can "weld-through' primer".
