im currently stripping a body and i used this stuff called "circa" i believe...well thats the brand name of it. its a spray on everything remover. used for furniture...its about $5 canadian...i sprayed it on. let sit for a few minutes and use a paint scraper it stripes right down to the primer with great ease...alot easier than id imagine stright sanding to be. i didnt completely strip the body with one can though...you'll need two
hope this helps a bit!
ps. you can get it at your local hardware store.
saftey:
this stuff is potent. read and re-read the instructions. youll need a respirator mask (a small gas mask) eye protention. chemical gloves...the works. you dont want this stuff on or in you.haha
