A short search reveals mixed reviews. Long time drying once applied for some users. One user claims it's a mixture of Boiled Linseed Oil, Tung Oil, and Urethane. I have no idea whether that's accurate. If it's not polymerized Tung Oil, then the lack of driers in the mixture can greatly increase cure times like you'd expect anyway from straight /pure Tung Oil.
Another user reports that they get the common water/white rings on their dining room table that they finished with the Bush Oil, but after a short time,the marks go away. This to me really suggests Tung Oil, more than BLO as the base oil.
They also state they don't have don't have problem with it since the white glass marks are never permanent and they've gotten used to the temporary marks on the table after a meal.
So, sounds like a regular Tung Oil finish for the most part, but since you'll never really know how you like, or dislike it , for your own application, go and get some if you're still curious. Sounds like it's made or sold in New York State anyway, so you're supporting your own local business community while you're at it...
