The good thing about the dry ice method is that it's real cheap to try and won't damage anything. I use it once and it worked. Others have not always had success. I had a silver dollar sized dent on a car that was caused by hail. On a very hot summer day I parked in the sun for a few hours and let the car heat up. At about mid afternoon I put a small piece of dry ice on the dent and within a very few seconds the metal under the ice contracted and the dent popped out without a trace. It only works if there are no creases in the metal so it obviously has limited applications. Oh, when the dent pops the dry ice goes flying and you don't want it landing on you.

We all like to think of ourselves as rugged individualists. But when push comes to shove most of us are sheep who do what we are told. Worst of all, a lot of us become unpaid agents of whoever is controlling the agenda by enforcing the current dogma on the few rugged individualists who actually exist.
