How can I remove dings from my car?

Two ways:

1 You need a blowdryer and can of keyboard cleaner. Take the the blowdryer and heat up the dent for about 1 min, then take the keyboard cleaner, hold it upside down and spray it all over the dent so you can see frost all over it. Wait...when the frost starts melting, you'll watch and hear a "pop!" that's the sound of your dent going away. Take a rag to wipe the dent area clean.

2 You need dry-ice. Same principal here, take the dry ice and rub it over the dent until it turns frosty, wait a few minutes until the frost drys, then repeat. You may have to do this several times depending on the dent, but slowly the metal contracts and dent pops out.
