Ps, you got me thinking in the other thread.
Yes...What I found worked best was a die grinder (straight and angled) with a round tipped carbide cutter and a seam buster chisel. If you don't have air, maybe find an electric equivalent.

Die grinders, straight and angled:

You'll also need seam buster chisels. Get both:

I also bought a spot weld cutter set, but found it easier to use the die grinder.

My process was to grind the spot or stitch weld thin and then pound in the seam buster chisel to get the spot weld to let go. Many are difficult to get to, so you'll need patience and creativity. At one point I had to cut some the bulkhead to get to some of the spot welds that are inside the box sections. In all about 75 welds.

Have fun...
