Brownells lists the Old Master's brand at $45/quart(!!). "specs: 100% pure, natural tung oil without additives or driers, for beautiful, hand-rubbed, in-the-wood finishes" Between Old Master's and Brownells reputations it's a brand to look for anyway. A quart is A LOT. Most of it has probably gone bad in the can and I didn't pay anything like $45 at the time. But it gave the finish I was looking for, pure or not. Bought a can of BLO at the same time, the tung oil came out a little less glossy on the test boards but otherwise the same.

Which explains a lot.
