Q&A for How to Remove a Dent in Car With a Hair Dryer

Compressed air can be found in many stores that have office supplies or art supplies and can be ordered online.

It works with metal too. Blowing with the hair dryer alone won't fix anything; once you heat the metal up enough with the hair dryer you have to push the metal from the inside of the dent outwards towards its original position until it gently pops back into place. Turn off the hair dryer and don't use the car for at least half an hour afterwards.

Heat up the damaged area, put on a thick leather glove, and push out the dent while holding pressure on the dent. Take a cold rag soaked in ice water and rub it over the heated area.

Probably, but there is a high risk of warping. Aluminum is a very light metal that warps easily.
