The pros make metal dollies shaped like the molding and small hammers to get them near perfect, then sand, then polish. The guy that does my stuff charges $50 an hour, and it looks like jewelry when it is done. He can fix anything, have seen him tig 2 pieces together and you can't tell.
That and at times I have to bend areas open and do fixes then bend them back.
Use a Black Marker as a Guide Coat. Once the dent is out you block sand. Paper then gets progressively finer till it is buffed with for me 3 grades Black Emery, Gray Emery, White Rouge and on some stuff Blue.
And a quick wipe with Wenol cleans it and keeps it up.
I just did some Challenger SE Type trim that goes on the rear of hoods fenders and doors.
Had to open some up to fix. Also widened the parts that slide on the hood so it could go on the T/A thicker hood.
