I'm finishing a new coffee table (no relation!) and am wondering about the underside. I've got lots of wood pieces, both expensive and not, where the underside is stained but not finished.
Never really thought of it before, since I've never finished or refinished a table, but is the underside left unfinished (poly finish, not stain) for cost/time savings or is it to let the wood breathe? In theory, the underside won't get any traffic, so doesn't really need a poly finish.
I've still got to finish the apron and overhang, but do I need to do the bottom inside the apron?
