The >'substitutes' are poor substitutes for the real thing. I don't do any auto body work except for minor dings. I use Bondo: <https://www.3m.com/3M/en_US/p/d/b40071783/> mostly because it's dimensionally stable. I may need to do some body work fairly soon. My Subaru is at 165,000 miles and I've been delaying any major repairs. I have a Harbor Fright auto body tool kit: <https://www.harborfreight.com/body-and-fender-set-7-piece-63259.html> but have never learned to use it. We'll soon see if "learn by destroying" actually works. >Haven't found any way around the methylene chloride ban, >which means there is no paint remover in USA now. Things >named 'paint remover' cost more now, they have nice >'environmentally friendly' green panels on the package, but >they will not remove paint. Agreed. I've had the same problem. I can't find a paint stripper that works. Aircraft stripper NMP (N-Methyl-2-Pyrrolidone) worked for a while, but was found to cause birth defects and other maladies. I haven't tried the latest substitutes: <https://www.socomore.com/en/paint-stripper-kemstrip-600-1000l-p.html> You can use a heat gun or IR (infrared) gun to strip paint. Also a combination of paint stripper and heat to accelerate the process might help: <https://thecraftsmanblog.com/heat-gun-vs-infrared-paint-stripper/> <https://thecraftsmanstore.com/product/ir-paint-stripper/> <https://eco-strip.com> I don't have any experience with these methods. Methinks the IR gun is worth trying. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558
