Dry Ice is a sham too, I bought a block one time, in combo with my heat gun & nothing.

 

go find yourself a good quality paintless dent repair person they are awsome if you find a good one ask to see some of there work or referances a good one will be able to tell you if the dent is able to be removed and they should be able to remove the dent and you shouldnt see any trace of the dent but with no paint damage to the area. thanks and good luck

 

dont use a lighter, try a hair dryer or heat gun next time
