  • Extension cord

  • 1 can compressed air

  • 1 dry cloth

Compressed air is a common tool for cleaning computer keyboards.

Small dent repairs can cost hundreds of dollars at the auto body shop. You can easily repair a dent in your car at home with items you probably have around the house. Popping a dent yourself takes less than five minutes, and can be done without damage to the paint on the car.

Step 1

Plug the hair dryer into the extension cord and take it outside to your car. Take the can of compressed air with you, and the clean cloth.

Step 2

Turn the hair dryer on to high heat. Aim it at the dent for one minute. Hold the hair dryer 2 inches from the surface of the dent.

Step 3

Hold the can of compressed air upside down and aim the nozzle at the dent. Pull the trigger and spray the cold liquid onto the dent for 10 seconds.

Step 4

Wait for the cold to contract the heated metal. You will hear an audible pop when the dent goes back to normal. Wait for the liquid to dissipate.

Step 5

Wipe the surface of the car down with the dry cloth to remove any left over compressed air.
