Not to run off subject, have any of you used a Mix of slurries? I have and am fairly new to the art. The thought of using a high polishing Jnat slurry With the Coticule slurry, the ways or combination and timing or watering down leaves many possibilities to experiment with.
I really like to see New progress being made in abrasive use and related technologies. The Gokumayo 20K is impressive advance, though over priced. MHO.
