I've tried quite a few methods of removing rust, bondo, old paint. I had never tried the 3M pads until today. They work better than aircraft paint stripper on the rear fenders of my '52.
It took about two hours to remove 5 layers of paint from a fender. It works great, and the metal never got hot. I had tried chemical stripper on this same panel, and it didn't work well at all.
I still like sandblasting better, but if you don't have access to a sandblaster, or your panels are so thin you are afraid of blowing holes through them, this is a good "backyard" way to go.
