Soda,plastic beads, etc.
Just looking to remove the clear coat and not do damage to the surface.
Am painting them black hammered finish.

FWIW - I did my stock alum. wheels and my cheap blaster and play sand wouldn't cut it. That clear coat is hard. A commercial blaster would obviously do better. I'd look at an oxide type. Primer covers any "marks" anyway.
Found the best and easiest was paint remover - did not mar the aluminum at all. Mine was only bad where the machined aluminum was on the outer rim edge. The rest was solid, sanded it all, etch primer and painted - looks great so far.
I masked that edge so I did not get it on the rest, carefully pit on stripper and used a 3m scotch brite pad and stainless brushes. Feather edged any slip ups or any remaining nicks and scuffed the rest with a pad.
If the entire rim needs blasted and you don't have a BIG blaster, I'd use stripper on the entire wheel.
