To remove a dent in a chrome bumper, remove the bumper from the vehicle, soften and heat the metal, and place a silicone mat and block of wood over the dent. Tap the wood with a mallet, and then check the smoothness of the dent.
- Remove the bumper
Remove the bumper, and place it on a workbench. Get someone to hold the bumper upright to prevent more dents from forming.
- Soften the metal
Use a rubber mallet to soften the metal by gently tapping the back of the dent.
- Heat the metal
Heat the metal with a propane torch, but do not overheat.
- Place a silicone mat on the dent
Place a silicone mat over the dent to prevent the dent from popping out the other side.
- Place a wooden block on the dent
Place a wooden block on the silicone mat. Tap the block with the rubber mallet, lightly at first and then gradually harder.
- Check the smoothness of the dent
Check the dent throughout the tapping process to make sure it is smoothing out. Continue heating and tapping until the chrome appears smooth.
- Replace the bumper
Remove the block and silicone mat, and then install the bumper onto the vehicle.
