Fellow wood destroyers, I'm finishing some clear fir doors and windows (interior), and I'm using Watco's Danish finish in natural, this stuff here: LINK It is absolutely perfect for the application, and I've been really happy with results. Still, I'm a cheap....er...thrifty sort, and I can't get past the feeling that I would make this myself for about 1/4 the price. I can get pure tung oil, etc from a local Woodcraft, and mix my own, but I'm at a loss on what/how to mix this stuff. Anyone have any suggestions? Stop whining and just buy the Watco stuff?? I'm going to be doing a bunch of CVG fir windows, which are completely dry after being unfinished for about 10 years. Thanks!
