At the risk of topic shift....

I have been reading this thread as well as the 31 page discussion with great interest. I appreciate all of the insight provided therein. I have a related question about earlier in the process...

How many times and at what point does one raise the grain/whiskers with water? I'm in the middle of a stock and did so after completion of 220 grit. I've now finished, dry sanding, to 400 grit. Should I be dousing the stock again?

Apologies if I am hijacking this conversation--not at all my intent. It's all related, at least, in my head.

Thank you,
Hoot
