Have at 'em, if you think you have a case. They claim tung as an
ingredient.

well, i read that and must have missed the part where they said "tung oil" is
one of the ingredients. it does say 'An oil-based finish ' and 'those who
admire the natural beauty of wood have relied on tung oil' but i don't see any
claim to tung oil as part of the mix. looks like marketing b.s. to me
