What experience is out there repairing minor stone pits, vs deeper or bigger chips?

I have several on the front spoiler that you can only find when rubbing your hand over the surface, perhaps as big as the head of a pin.

No visible pit, but I haven't examined the surface with a magnifying glass. They're that small.

Clay barring didn't remove them. And I'm very reluctant to scuff up the area trying to sand them off 2000 grit sandpaper.

I have Griot's #3 polish, but haven't tried it yet.
