these are old formbys high sheen tung oil mix, that's a new bottle I had on the left, I put a few bottles with my paints, not sure what to do with all of them.
They were still sealed, broke seal on one, and rubbed it onto a piece of walnut scrap, it seems fine.
does this stuff break down? Im waiting on the morning to see how it looks.
The date on the new bottle I just purchased recently says 2002, the old bottles say 1980.
