I'm building some tables out of construction grade 2x4's, gluing up and squaring off. (RE: http://www.sawmillcreek.org/showthread.php?t=23894 ). Even after planing the surface they still need some patching. They will be indoors, primed and painted, subject to occasional spills and cleaning.
What should I use as a filler? If wood putty, please specify a brand you like, I have had very little to no success with the stuff in the past. Can I simply use joint compound and prime over it?
