Thanks for the info...I`ve used tung oil in the past, but, never with clear...That`s why I put the question mark after the sentence...The OP wants a durable finish, so, I thought I would suggest clear coat after treating with tung oil...I now know they are not compatible...Cheers
But Tung oil may be burnished and or waxed/polished... Just, as said by others, not clear lacquered. Same goes for any other of the oil finishes (Scandinavian, Linseed,etc etc).
Cheers
