The last thing you want is pure oil with the consistency of honey. It should be very thin and runny.
Unless they lied about no driers/additives (could be) IIRC correctly the tung oil hardened a little faster than the BLO which I'm assuming had a drier added. But not enough difference to make an impression. Also IIRC Newell in his book said that a drier wasn't necessary for tung oil and you can get crackling problems.
Next, how many angels can dance on the head of a pin I suppose.
Test board whatever you come up with, also the little practice applying the stuff couldn't hurt.
