I previously purchased some formbys tung oil finish at the big box store, only to find it was actually a blend of oils. Looking online it seems there is various terminology for tung oil. 100% tung oil, pure tung oil, 100% pure tung oil, tung oil finish, tung oil, fast drying tung oil. I plan on going to my local woodworker supply store to buy some on the way home today and want to make sure its just tung oil with nothing else added. I am not sure what brands of it they carry. I know they carry Old Masters products, and I saw on Amazon that Old Masters makes a Tung Oil and a Pure Tung Oil. I am guessing “tung oil finish” and “fast drying tung oil” have additives, but is it safe to say the others are just tung oil and nothing else added?
Thanks
