I was using a heat gun and scraper to remove the undercoating / gunk from inside the fenders and the front "tub" where the fenders attach. There are small crevices that the scraper won't fit in, so I was carefully using a propane torch to burn the undercoating , and then I could use a wire brush to remove the remains.
All was going well until I saw flames inside the passenger side of the car !! I'd like to say I didn't panic, but truth be told, I was pretty excited....not in a good way. Thankfully the carpet that was burning was flame resistant, and burned slowly, giving me time to get my fire extinguisher on the job....WHEW, this scared the pants off me !
It turned out the rocker panel I was using the torch on had a big old rust hole that allowed the flame to reach the interior carpet!
Well, the passenger side carpet was ruined, and the interior of the car was covered in soot from the flames.
The only course of action was to start taking apart the interior and cleaning things up the best I could.
