Remember that post? Well I posted to see if folks had ideas for removing large 20 year-old hail dings from my triumph. Well, I tried it. It may have worked a little for a few that I could apply both heat to the underside and dry ice to the top. It was suggested that I use a hair dryer (instead of a torch) so I wouldn't fry my paint on the inside. I heated the underside until it felt pretty hot to the touch and was starting to smoke the underside and then applied a chunk of dry ice. It took a long time with a 1600 watt hair dryer to get the thick triumph metal hot. Then I would apply dry ice on the top side. (Hard to manipulate with gloves on) I repeated the procedure several times for about 5 of the 15 or so places on the car and could maybe see a little improvement. Maybe the thickness of the metal or time lapse or insufficient temperature contrast with a hair dryer was the cause. Was also hard to get a "chunk" of dry ice in full contact with the dimple--- So-- It's back to the molly and hammer and putty to finish the job. Anyway, I tried and had some dry ice left over to make some spookey bubbles for the neighborhood kids.

My guess is you have to get the metal much hotter. Which will then burn the paint and then you have to repaint it.

I think they use a heat gun,...and you need to be careful to not blister the paint.
I still think the more modern methods of paintless dent removal are probably better.
