What do most people do for finish, sand while wet then warp?
or not sand at all, and just leave.
or what?
and what if any finish do you guys use on the bowl after its warped.

I just completed a bowl from a piece of crabapple... Turned it to final

I did a hand sanding after it finished drying, then several (about 10)
coats of shellac and finished with a paste wax.
