Dominator ceramic call help

[cannonball]

I got one of stumpy's Dominator ceramic call today on a trade. This call sounds awesome! I don't have any idea on how to condition ceramic and I don't want to mess this one up, it's vest worthy! Can someone please tell me the correct way to condition it?

Sanding stone, light pressure.

Ive also used 80 grit sandpaper, and if I get oil on it from my fingers then an alcohol pad (like for diabetic testing) is what i use to clean it with then follow that with the paper or stone.  The great thing about ceramic is that maintainence is very low compared to copper or even slate.  Good luck with that call.  I hope you call in a big one with it and shoot him in the face.
