I assembled my latest project (a blanket chest) yesturday and I
contemplated prefinishing it before glue-up. This should make glue
clean up a lot easier. I can see two potential problems with this: 1)
finish will weaken any tenon shoulder glue adhesion (finish
surrounding a mortise). 2) the act of clamping can scratch the
preapplied finish. Take the poll.

I pre-finish my projects. Before applying the finish, I mask off all
joints and glue-up areas. I don't worry about the shoulder joint where
the glue would be end-grain to side grain, just the mortises and tenons
themselves. I don't do this with dovetailed drawers, but do pre-scrape
the
inside in order to make applying the finish easier. I also pre-finish the
drawer bottoms -- it keeps glue from sticking to them.
What, just one hand-rubbed coat of Waterlox, or something thicker?
Anything should make a big difference with glue.
