3M makes a product that you put in your angle grinder. I believe it is called CleanNStrip. I used it on my truck. I have found that one "pad" lasts for one body panel. One door, one side of the hood, one fender. I haven't done the box yet. The disks are about $10 each and the "adapter" they sell is around $5. No warp. Removes everything including old bondo.

I don't work for 3M but it sure is a fine product for restoring old cars.

When you get the old paint off, if there is no surface rust, immediately wipe it with laquer thinner and spray it with epoxy primer. If you had surface rust, hit that with DuPont "Kwik Prep" or similer before you epoxy.

The picture is one I lifted from 3M's website. I have found this product at Menard's and Northern Tool. I think they are a buck cheaper at Northern.

I wear a respirator when I remove all that old paint. I have no idea what is in it but I'm guessing there is some lead.
