Guess I should clarify - the advice I've read (Newell and others) is not to wet sand but brush on varnish to fill grain with just resin. No filler. Somewhere along the line I read it's ok to wet sand after the first coat as the "dust" is just resin. Thought is the fillers make the finish look muddy. Does to me. Never hurts to do a practice piece and make up your own mind on what works and looks good to you.
