It would not be my choice... I still prefer using a torch to soften undercoat .and a wide scraper to remove it...



I'm using a heat gun but a wide scraper as well. Mine seems to come off pretty easy, so far. While I'm on this subject and not to deviate from the OP but here's a question related to this:

What to put/do to the metal after removing the undercoating? I would think you need to do something soon to prevent anything happening to the metal. In my case, it could be a while to take it to a body shop(if that's the process)
