Watched a guy at the Pomona swap meet fix a dent with a heat gun and a can of air
I was at the Pomona swap meet two weekends ago just hunting for cheap trim clips when I stopped at a booth where a guy was pulling dents out of a beat up Civic fender. He wasn't using a stud welder or a slide hammer, just a heat gun and one of those cans of compressed air you use on keyboards. He heated the dent until it was hot to the touch, then flipped the can upside down and hit it with the cold spray, and the metal popped back out with a loud crack. I stood there for maybe 20 minutes watching him do it on three different dents, and two of them came out clean enough that you'd barely need filler. He told me he's been doing it 15 years and it works best on shallow dents in flat panels, but you can ruin a panel if you get it too hot or do it on creased metal. I tried it on a junk door in my shop that same week and got one dent out pretty good and cooked the paint on the second try. Anyone here mess with the heat and cold trick? Curious how hot you let it get before you back off.
