How to Remove Pit Marks in my 68 Tail Panel

They look fantastic! I’m curious because you didn’t re-anodize did you consider putting on some clear coat?
None of my aluminum trim has been re-anodized, and it looks great after 7 or so years after being polished. It's one of my daily drivers, and I've done nothing but wipe them down when I wipe down the car with detail spray and a micro-fiber towel. It simply doesn't need it, as far as I can tell.
