I called Minwax, and spoke with a manager. I asked him for the % of tung oil
in Minwax Tung Oil, he said in a SA manner that he was not going to give me
Minwax's trade secret, so I quit using the stuff. I now mix my own. I use 1/3
polymerized tung oil, 1/3 spar urathene, 1/3 turpentine. I like the finish,
and I know the % of tung oil in my finish.
