Burnishing a hard finish stone is artificially creating a face that has been well used for years. Which is why you do not necessarily want to lap a newly acquired old Ark, try it first.
Arks are so hard, that cutting the face with loose Silicone or Wet and Dry will leave a rough surface.
Burnishing with hard carbon steel and lots of pressure will knock the tops of grit off and grind smooth the cutting grit leaving a smoother less pointy, aggressive grit, similar to well used sandpaper. It is the same grit, but is less aggressive cutting. With sand paper we want aggressive cutting grit and paper, but with a finish stone we want to polish smooth. It may take a few more laps but, time is relative.
It can take many hundreds of laps to properly prepare an Ark face and will continue to improve with use, which is why you do not want to slurry a burnished, finished ark stone, though I have tried both ways and still finish on a burnished stone. Some Arks on some razors perform well with a thin slurry but YMMV depending on a variety of variables.
Arks should be used with a straight, finished edge, you are just final polishing that, may itself take a hundred laps or more depending on the condition of the edge and the prep of the stone.
Done right you can thin slice tomatoes with your cleaver as a by-product.
