dry ice for dents?
- Thread starter JUNNIEIV
- Start date
I tried it on hail damage on a '92 Z24. It doesnt work.
The supposed theory behind it is that if you can heat the sheet metal then apply dry ice to it, the metal will regain its "memory" property. The Dry Ice will stain your clearcoat more than anything.
Sorry, I'll leave my dents to professionals....

Dry Ice will condense metal and thereby shrink small dents on your car.
Condense metal huh? You gotta be kidding.
I heard that the theory (with ice on the top of the dent and a blow torch on the other side under the dent) is that when the ice melts and boils off it causes a low pressure area over the dent and then because of the higher air pressure on the other side of the dent (side with the blow torch) that the dent will *pop* out because of the difference in pressures.:nixweiss

How much of a difference in air pressure can there really be? There has got to be a ton to get them metal to pop. I think this is physics being taken too far.

The reason the dry ice is cold is because of the latent heat required by it to change from a solid to a gas. It needs to be gaseous at the temps we live at, and to get there it has to suck heat out of something, basically anything it comes in contact with.
That pressure stuff...whatever.
The reason the dent "pops" out is because you're making the metal shrink there. Cold = shrink. Heat = Stretch. They did it with ice and a blowtorch because they needed a big temp diff and didn't have any dry ice.
