How can I take a dent out of a plastic bumper?

Updated February 21, 2017

Rear bumper dents happen after accidents, and are often difficult to remove. Sometimes the dents are pounded or pulled out with heat. Fixing a dent at home is less expensive than taking the car to a bodyworks garage for repair. The entire bumper is frequently replaced if the dent is too severe.

Wash the dented area of the bumper. Remove all dust, dirt and debris.

Turn on the hairdryer; move it in a circular motion over the dent. Do not leave the hairdryer in one spot for more than a few seconds. The dent might pop out after a few minutes.

Tap the area around the dent with a hammer. Do not create new dents by hammering too hard. The tapping creates vibration; the combination of vibration and heat frequently pops out dents.

Move the hair dryer in a circular motion while lightly hammering. Do this for 10 minutes and the dent might pop out. Repeat the process if the dent remains unaltered.
