Putting together a grit order. I still have 500 SiC but it looks like some people use 500 AO in the vibe? Should I add some 500 AO to my order and keep my 500 SiC for the rotary?
The Rock Shed has both and they are similar in price. Is this just a preference, or is one better for rotary and one for vibe?

I use 500 AO in a UV-18 vibe on mostly preform cabs with good success.

I don’t do vibes but 500 is the same size whether SiC or Ao. SiC is a tiny bit harder.

Aluminum Oxide will eventually breakdown into polish if it rolls long enough.
