There is a lot of info here on hotrodders in the Wiki Section. , My willys had about 6 coats of paint and I scraped the top layers off, a lot of chips, no gooey mess until I got down to the bottom layer and used stripper. I also use my 3500 Psi pressure washer, to remove the stripper-paint that doesn't come off easy with a scraper. It will remove a lot of paint just slower, I also have a wet blaster from northern tool for heaver metal parts, frames ,axles, etc. water and sand, NO dust, just a wet mess, I had my nash roadster blasted by a guy the restorations guys use. He knows what he is doing and doesn't warp panels but cannot get out all the pits in sheet metal.
