Tung oil
Bob Rogne
I just found 2 partial cans of tung oil I left in Az. for the summer and now find that they have thickened uo.
Is there any solvent or thinner that can be added or should I just dump it?
Thanks
Bob

Sounds more like an ersatz "tung oil" product or boiled tung oil with driers that's polymerized. Not worth salvaging; replace it.

Is it tung oil or "tung oil finish"?
Some "tung oil finishes" have little or no tung oil in them. Tung oil polymerizes on contact with air and what has polymerized won't soak into the wood, but so long as the tung oil is liquid enough it can be rubbed onto the wood surface and leave finish behind (with the benefit of not needing weeks to cure). If it's a "finish" then it depends on the composition of that particular finish.
So the answer is "it depends, test some on scrap and decide if it will work for you".

If it doesn't say 100% pure Tung Oil on the label, then it is just a finish. Usually, when a finish comes into contact with air, it begins a natural process of polymerization which cannot be stopped. That's why I bought several bags of marbles. I put them in the can to raise the level of the Tung Oil and keep the air out. Works marble-ously!
A few years ago, Sutherland-Welles was formulating and shipping most if not all of the Tung Oil products in the USA, according to the man I talked to. A wealth of information and knowledge and easy to talk to!
