Undercoating removal with heat?

Hi,

So we all know that removing undercoating is a bugger of a project. I ran across the photo below showing someone using a flame/torch to heat up and soften the undercoating. Subsequent photos show the undercoating being scraping off with a scraper and wire wheel.

I did an accidental small test using this method when I used a MAAP torch to heat up a rusted/stuck suspension bolt for removal and burned the nearby undercoating on the front inner fender. I ran to get a scraper and wow, the undercoating sure came off easily!

I was wondering if heat like this could damage things... possibly cause warping etc...

Any thoughts?

Thanks,
Tom
