you are a life saver. i have been looking for that. I knew you could do it with some sort of ice. it is an old hot rodders trick. Wasn't sure if it was an application of heat first then apply a bit of ice or just dry ice.

Will try and give it a go on the weekend and let you know how it works

I don't imagine it would be that easy to obtain. It could be quite dangerous.

Good method for fixing hail damage

ps Dry Ice now comes in pellets ideal for this, about $6.50 a kg from BOC

i tried it and it didn't work. i held a 1.5kg bag of the pellets on the door of the cruiser for about 15-20 minutes and no go. the dent looks like it's from a small ball pein hammer and the ice bag had a surface area of a small saucepan.

and yer, dent still there.

but, i did make my orange juice fizzy. and blew up some coke bottles.

I think the idea is to have a small surface area of ice in the middle of the dent, not a whole bag, to cause the metal in the imediate area to contract, thuss pulling out the dent

I trried dry ice yesterday on a dent similar to the one in the video. I only put two or three pellets into the centre of the dint. It didn't pull the dint, but changed its shape slightly. I played around with for naother wile, but couldn't fix the dint. It either requires more experience or doesn't work at all.
