Patchy grit on the 60
Poltava Premium Metallic CBN Stone [6" x 1"]
I recently received my 120 and 60 grit metallic cbn stones. The 120 grit feels fairly consistent across the surface like a Venev resin bonded 100, but the 60 grit metallic cbn has some fairly sizable patches that feel smooth to the touch and these spots feel a little lower than the gritty parts of the surface. Can I flatten\prep these stones before use with a course water stone or is buying lapping supplies also required? The description says Poltava metallic cbn stones don't require preparations but I think one of mine slipped through QC.

I would suggest coarse grit silicon carbide (or very coarse sand) on a flat surface to try and remove the top layer of your 60 grit. It will likely quickly eat any waterstone that you use on it for breakfast and leave the surface smooth. You need coarse, loose grit that can be replenished while flattening.
