I defiantly need some thing that leaves no visible scratches. I'll probably keep trying with the DMT card that didn't really scratch.

When I lap my Nakayama (My shobu is redundant) I use the Shapton lapper for a bit then onto the 1200 and then spend an age with a tomo trying to get it smoothed out. Maybe I should look at sand paper?

Reading than on your left hand side appear more scratches, I should mention; it's a good idea to turn around regularly the surface of the stones, 180 degrees, and use evenly distributed, not too much pressure for uniform wear. As for lapping, you can use a fine man made stone (preferably hard too) under running water and rinse repeatedly to polish the surface of the stone. Safer than sandpaper, and less time consuming than nagura stones.
