Well, if you got the bevel fully set most it should need is laps on the 12k until it stops improving. It's a pretty slow stone. When using it to finish off an 8K stone I'll do 100 laps on pure water, and another 100 on a thin shave lather.

If I were coming off the sand paper equivalent of a 2k home, I'd probably make as thick a slurry as I could with the rubbing stone and work the edge while diluting to polish away the 2k stria.
