It should work
I had a woman in Oklahoma back into the aluminum bumper of my 2003 International, leaving a small dent from her bumper guard.
I took the bumper off and hammered ot out with an auto-body hammer on a padded board. The only reminder was a blemish in the polished finish which I could never quite match to the remainder of the bumper.
It took my largest screwdriver and a wrench on the shank to get the screws holding the bumper out.
