Basically it uses a piece of dry ice, placing it over the ding causes the metal to contract and the ding disappears.

I haven't tried it but here is the video. i just felt that it may help someone who needs it. It may not even work completely but it is worth a shot.

After reading some of the comments, and the pdr guys bashing it. some points.

the metal must be hot. if it is cool out heat it with a hair dryer.

If you can't get dry ice, buy a can of air duster for computers and turn it upside down and spray it on the metal. the liquid refrigerant has the effect as dry ice.
