    Fill a pot with water and bring it to a rolling boil. Carefully pour the water over the surface of the dent to heat up the metal. Allow the metal to flex and return to its original shape.[1] If the bumper is plastic, push the dent out from behind after you pour the hot water over it.[2]
    • Don’t press the dent out of metal like you would for a plastic bumper.
    • You may not be able to remove all dents from metal bumpers.
  2. How.com.vn English: Step 2 Pour cold water over the area to help the bumper retain its shape.
    If the bumper is plastic, keep pressing out the dent from the inside until it’s fully removed. Then, pour a pot full of cold water when you’re finished to solidify the bumper.[3]
