I sat one of my clamps atop my Coti the other night. The rubber feet of the clamp transferred onto the Coti and not even my DMT 325 could get it off after a normal lapping. I'm sure it will eventually go but geez, it's kind of a bummer. Didn't seem to effect the ability of the hone to do its job, but then I'm relatively new to honing. Anyway, thought I'd share the mistake for other noobies.
