Well as I've said before, linseed oil doesn't really dry!! It does oxidize, slowly, over time. It will however become sticky to the touch, again, for many years. Tung oil dries to a hard surface than linseed. In any of the normal forms and while tung is more resistant to water, neither is water proof. That's why they have to be waxed. There are several methods for application of either. I prefer TruOil but each to his own.. It's what makes life interesting.
