I understand sanding with progressively smaller grits.
I understand the idea of wetting the piece to raise grain.
Should it be wetted and allowed to dry between each grit? What's a good point to start?
I'm refinishing drawers.
How much of the drawer should I wet - all? face only?
It looks like there's a very thin coat of clear finish on the sides of the drawers. When sanded it produces a fine white powder. What is it likely to be and should I replace it after sanding?

Face only, maybe not so wet. No need to wet betwixt each grit. Just
clean all previous grit. The white powder is probably some type of
finish, alcohol, water or oil based, so check with the appropriate
solvent. Drawers aren't usually finished unless they're a particularly
"movin'" species, so I'd suggest a shellacking (sp), at least. If you
want. It'd be nice to know the type of wood you've got to work with.

The idea for wetting to raise the grain is to be able to sand of the
resulting fuzz, and the fuzz only. If you cut past the fuzz, you need to
re-raise the grain. With this in mind, grain-raising between grits is not
necessary.

A dewaxed shellac sealer coat will also prevent grain raising.
You can also use a water based sanding sealer, which will both seal
and raise the grain, making the sanding of the raised grain go better!

Ok, First off you use the water to raise the grain ONLY IF you are going to
use a WATER BASED finish.
If you are going to use an OIL BASED finish use no water at all.
Water based finishes will raise the grain, hense you dampen the surface and
do a final sanding before applying the water based finish.
Oil based finishes do not raise the grain and require no special water prep.
