How to Hammer Out Dents in a Chrome Bumper
Polish your chrome bumpers regularly. (voiture jaune image by indochine from

The bumper on a car is a safety device that cushions the impact of a collision. Since it is the part of the car most likely to come in contact with a solid surface, it may get a bump from time to time. If you have a chrome bumper, you may be able to smooth out indentations yourself, and save the cost of an auto body-repair specialist.

  1. 1

    Remove the dented chrome bumper from the car by releasing the bolts holding it on with a wrench. You will have easier access to the bolts if you use the steering wheel to turn the wheels all the way to one side.

  2. 2

    Set the bumper face down on a soft surface like a towel spread out on the ground. Don't rest the chrome on anything rough like asphalt or you will scratch the finish.

  3. 3

    Hold a small acetylene torch flame near a dent in the bumper until the metal is warmed through. The flame should not be close enough to leave scorch marks on the metal.

  4. 4

    Tap the highest point of one of the dents with the ding hammer. Work slowly from the middle out until you reach the edges of the dent and the mark is gone.

  5. 5

    Heat each dent and tap it out in the same way until the bumper is free of any dips.

Tips and warnings

  • You can use ding hammers to remove dents in any of the metal parts of your car.
  • If the dent cracked through the chrome you will need to take the bumper to a bodyworks garage to be re-chromed.
