1972Chevy - You didn't say how thick the paint is that you are wanting to remove, but if it's already been painted multiple times, here's another idea. Years ago i bought a Camaro that had been painted 3 times and it was cracked all over. I found a hot razor blade holder - it looked like a soldering iron but had a blade holder on the end to accept single-edge razor blades. I used that (and about a dozen blades) to take the top 3 layers of paint off down to the original factory finish. Then finished it off with a D/A.

FMX - I gotta try those things!
