8 inch pad on an air sander, that I can run slow. 36 or 40 grit. strip the corners by hand with 40 or 80 grit.

I can strip the car in one day... and it's already sanded for primer. Uses less than a box of sanding discs.

Then I metal prep and bury it in primer.

Great adhesion... low materials cost... minimal hours... no problem with stripper residue affecting the paint... what else do you want? :-)

(Do not use this method on fiberglass. LOL!)
