Reply to "Remove under coating any recomendations"

The worst and messiest job I have ever done on a car!!!

Heat Gun and Scraper: I used a heat gun and scraper, like Julian, which is how I removed most of the stuff. Note that the scraper will not slide smoothly on the metal beneath to cleanly lift off sheets of the undercoating because it hides a multitude of manufacturing sins - weld splatter, rough edges, etc. And be aware that you will burn yourself with that heat gun - at least I did on several occasions. Then you'll need to thoroughly wipe out all the spot weld dimples and crevices with lots of lacquer thinner, as well as rub down the entire surface to remove the remaining undercoating film.

Wire Wheel: I also tried a wire wheel on a die grinder - that only threw crap all over the garage, and in my hair, ears, clothes, etc.

Torch and scraper: I also tried a torch to heat the stuff and scrape it off - this is fine if you like noxious fumes and inhaling carcinogens.

If I were to do it again, I'd use aircraft stripper. A friend and his daughter stripped his entire engine compartment in about 4 hours one evening to prep the car for paint. I thought I could save the paint beneath, but it was a mess by the time I was done. Aircraft stripper would have been much faster and easier I think.
