For a filled surface I use steel wool to rub in the first one maybe two coats of tung oil. The wood fibres the steel wool shears off should mix with the oil and pack into the pores. French polishing on furniture accomplishes the same thing using Rottenstone and Pumice as the abrasive in a shellac binder with mineral oil as a lubricant. Tung oil is a penetrating oil, that seals the surface of the wood. Once its sealed it won't take any more so your building layers on the surface, and Tung oil doesn't do that very well. You'd be better to switch to a furniture oil that builds on surface for the last coats.
Free advice is worth exactly what you payed for it.
