For tumbling rocks, what do you all prefer, AO or CPP? I ran out of CPP and used AO in my vibe. Since they were already somewhat rounded I went with 2d, 3rd and polish stage in it. After leaving the rocks for 3 days in AO, they only seemed to come out worse. I've done this before with other similar rocks, but instead used CPP and they have come out really nice. Those polishes seem to look so much the same, yet for me the CPP is by far the better one. No more AO for me. I'll probably end up using the AO in the rotary and see what happens then.

I have noticed that your best shine is achieved at 24 hours with AO in the vibe. The tumbler it seems fine. If you continue the polish in the vibe, I think you need to add more or just complete at 24 hours with AO because I suspect the extra friction does not help the stones at all. Just a view. Fran

Isn't AO an CCP the same material with the difference being the grain size? I think regular AO is .005 mil and CCP is .003 mil. I may be wrong as to the difference since I have not been able to find much info. on CCP.
I use AO as a pre-polish in my rotary tumblers and CCP as a final polish.

I use AO for 24 hrs in my vibe and I'm happy with the results.

AO comes in many forms from 600 grit to submicron. .5 and finer works very well in vibes while the 3-4 micron stuff commonly marketed for rotary tumblers works only so-so. The 600 and coarser stuff would be prepolish only. CPP is a mystery product. The only thing I know is it is a "pyrochemically produced compound" and is the least costly of all polishes. That is why it comes with most tumbler kits. The people that like CPP tell me they use several tablespoons in a 3 lb. rotary while the better (more costly) polishes only require a couple of teaspoons.
