The first layer of finish (the pore filler) is always exciting, as the color of the wood begins to show. I use CA glue as a pore filler, because it goes on fast, dries fast, sands wonderfully to a dry powder, and ‘wets’ the wood to really show things very much like shellac. Also, when sanding it back, if you oversand a bit into the wood itself, going over with another layer of CA blends things in perfectly.
