A very old school body man taught me a useful trick for getting dings and not so small dings out of trim and metal.. While watching TV, use the round end,back side, of a large spoon. Tap across the ding at a very slight angle and keep tapping. Eventually you will see the ding/dent start to rise up as you slap away. Finish with appropriate sanding and polishing. I learned this doing headlight rings for an old model A Ford and it does what it is supposed to do.
There is also a tool called a slapping file, known as a “slapper” that will work the same on body dents, but having never done this, you will have to experiment. Tool should be available at a body shop supply store
