I had to get this one so hot to get the wrap loose, it burst into flames a few times. So I had to go real, real slow with a thin, sharp, putty knife. Heat, scrape, pry, pull, curse, then repeat as needed. Remember! safety first.
Yeah, anything pre-1965 can do that pretty easy. I've had it happen several times. It might be kinda funny what the neighbors think, 'cause when I strip wrap off of shells I do it outside in my driveway. When one catches on fire, I just give it a gentle "roll" down the drive and it usually smothers the flames pretty quickly (you know, the old "drop and roll" idea?). I actually try to have enough control that it don't happen, but hey, it's for sure not an exact science!
