practical dent repair

While brothers browsing the net, I found something like that. man warms the buried place in the bonnet with a hair dryer first. then it squeezes liquid carbon dioxide there veeee result. The dent is gone. what are your comments? erkankurnaz 2009-08-22 23:37:38

I have seen this process before, some say that it is with refrigerant and some say that it is also with air conditioning gas, but it was not very convincing to me.

Considering that the heated metals are expanding and the cooled ones are narrowing, it made sense to me. man uses the temperature differences

but maybe it can only work on breasts that can throw away very easily =) thanks for sharing anyway

Will this application harm the paint? Do you have friends on chemicals in the forum?
