How to Fix Your Car Dent with a Hair Dryer

Surface damage on a black vehicle.

If you've ever dinged your car—or worse, a friend's or parent's car—and caused a dent, you know how expensive it can be to fix. A two-second mistake can end up costing hundreds of dollars, but you can save yourself repairs costs and a headache with just a couple of household items.

What You'll Need

Luckily, if the dent isn't too nasty, you can probably fix it in just a few seconds. You'll need the following:

  • a hair dryer (or heat gun)
  • can of computer duster spray
Hair dryer and can of compressed air on a shelf.

Heat Dented Area

Take your hair dryer and start thoroughly heating the dented area. Do this for about 20-30 seconds. If you're using a heat gun, be careful to not damage the paint. Use a circular motion to make sure the full area is heated through.

Spray with Computer Duster

Immediately after you've heated the dented area, spray it with the computer duster, but make sure to hold the can upside-down. This will cause the CO2 to release super-cold—you may want to consider wearing gloves.

Watch & Wait

Once sprayed thoroughly, just sit back and watch. You should be able to hear the metal popping, and in a few seconds, you'll see the dent release back into the normal shape. Bam!!
