I've got an old road bike with polished steel fenders, the rear one of which unfortunately got bent during transport:
As you can see in the lower half of the photo, the two sides of the fender were bent towards each other, causing a "crease" to appear in the middle of the fender.
On the left side of the fender, as pictured above, I had tried to use some pliers to pry the side "away" from the other one in an attempt to fix the "crease" in the metal. Unfortunately, this just made a plier-shaped dent at the end of the fender.
Lastly, on the right side of the fender, as pictured above, there is a somewhat shallower and "wider" dent which also appeared after transporting the bike.
How can I re-shape the fender so that it is not "creased" and not dented?
