The ones declaring themselves 100% tung oil, otherwise, suit city. Now tung
oil finishes of various types abound. As noted elsewhere, they usually
contain thinners to make them flow better, driers to make them cure faster,
and perhaps resins of different sorts to make the film more wear-resistant.

Are any of the products which call themselves Tung Oil actually tung
oil? Most seem to be thinned varnish, which I can make myself quite
cheaply!
