Well, the powder I use in my kitchen knifes leaves a mirror (not near mirror, real mirror) finish on the edge, so it should be fine.

Anyway, the kit Gunner has sent me has some 0.5 Crox in it, I'll test booth my "painting" crox and the stroping crox to see if they have any sensible diference. I'll post my findings here.

A mirror finish is something that depends only on the scale of observation.
A norton 8k gives you a "mirror finish", as probably would stones with grits like 6k, 5k. With a bad chromium, makes no sense using it after a good stone like the norton 8k.
