Subject: Re: Dents removed with Dry Ice
Okay, here's the poop. Although I have never tried this myself, it's
only because I don't have a supply of dry ice. If anyone wants to
correct my technique, that's welcome.
On a very hot summer day get the region of the dent heated up. Too hot
to comfortably rest your hand. Now, take a piece of dry ice in your
insulated-gloved hand, and work around the dent in a slow inward
spiral. The thermal contraction of the metal around the dent will pull
it out, sometimes to the original appearance. You may need to do this
several times before success is achieved.
I have also heard of impressive results from a teaspoon firmly rubbed on
the inside of the dent for a short eternity - if anyone has done a
bas-relief in copper in High School art class, they know the technique.
Rub, rub, rub....
