Thanks Blossomforth -
I bought a 3M paint and rust remover at the autoparts store but I think it's not the right thing to use.
I used a number of different things today: Aircraft decal stripper, Goof Off Heavy Duty, Blow Dryer, scrapers and a 3" putty knife. The blow dryer did well until I got to the baked on decals. Then I used the aircraft decal remover. It worked better than expected but not perfect and took several sprayings and scraping. I ended up removing paint around the baked areas. I then used a glass sticker scraper to strip off the excess vinyl that wouldn't come off. Been quite a job. Next is removing and cleaning all of the glued on chrome coated plastic along the rocker panels. The kid that owned this put so much crap on it. The plastic crome crap is going to be removed another day using the blow dryer and the 3" putty knife. If I get this all done by summer, I'll sand and repaint the areas where the stickers and decals were. I'll need advice on how to do that when the time comes. Until then, it's Guiness beer time.
