Query: Not tung oil, but a varnish

Note that this is labeled as a tung oil "finish," and not as tung oil itself. The reason is that this is a wiping varnish designed to produce a similar look to that of tung oil. It may look alright, but do not be misled into thinking it is something it's not. Unless it is labeled as 100% pure tung oil, and the directions tell you to thin it with mineral spirits, you don't have the genuine article. It's deceptive marketing, frankly.
