Beautiful form Michael. I have used paste wood grain filler from McFeelys with good success. You can tint it if desired. Brush it on, let it set and then wipe the excess off. Let dry and sand. Does a good job and is much quicker than sawdust and ca. It's just meant for porous grain not actual holes.Thanks Gabriel! Great question. I’m not filling the pores in on this one. I’m finishing with oil/varnish, so I’m not too concerned. If it was a lacquer finish I’d definitely fill via the dust/CA method.
