Lapping new Naniwa 12K stone
I apologize in advance for the newbie question. I just acquired a Naniwa lapping stone and a 12K super stone. I saw what looks like instructions for using the lapping stone on the box that showed something from a small bottle (does not look like water) being poured onto the stone to be lapped. As all is written in Japanese, I have no idea what this might be. In the videos, all that is used for lapping on a water stone is water. Is something else required for the 12K super stone, or should I just proceed with water?
Thanks for you reply.

Interesting.
I lapped mine with an old DMT 320 and tap water. It took about 5 minutes and I only needed to remove a tiny bit. It came much flatter than the Nortons I have seen.
In truth, I probably removed more than really necessary in effort to get one corner that dipped slightly (perhaps 0.25 mm?)...I could have simply marked it and just avoided that corner.
