I've been thinking about getting a DMT for a while now. I plan on using it specifically for maintaining the flatness of my stones by doing periodic lappings between razors.

I know that the D8C is the one most recommended for lapping duties, but I've been using 1k sandpaper on a granite tile to do my lapping lately and I am wondering if others use some sort of wet/dry paper to finish the surface of their hones after lapping on the D8C.

If I'm going to have to use sandpaper to smooth out the stone after lapping, there doesn't seem to be much point to getting the D8C. I could just spend the money on sandpaper instead.
