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