Hello Everyone !

I've bought a Charnley Forest hone couple of days ago...it wasn't lapped so I did it with a DMT 220 extra coarse, finally it became flat, but the surface of the hone is not the "smoothest" because of the DMT. So what can I do to make it superb smooth ? Is it a good idea to put some high grit water sandpaper on the opposite side of the DMT and refine the surface on it ? Or any idea?

Does gun oil works on it ?

Thank you very much !
