Just purchased a 12k Naniwa stone and was wondering for those of you who use 12k stones, what do you do after the 12k, if anything. I know it is a personal preference sort of thing, but was just curious what works for you. Let us know what you use and how many laps you do. I was thinking of purchasing CrOx on Balsa or maybe Diamond spray on felt. I know some move to a 20k or Zulu Grey stone, or a JNat.
