I applied pure tung oil to all my kitchen cabinetry.
Here's what I know.
Pick tung oil if you want a matte finish. It takes much time and effort to get a glossy finish. I like matte finish myself and that is what tung oil wants to be.

Tung oil cures, not dries. It's a SLOW reaction with oxygen in the air, full curing takes months.

How to apply - first coat is a generous application of tung oil thinned with 50/50 mineral spirits OR if you want to alter the color, a stain can be used as the thinner.

Let the first coat penetrate for an hour, then wipe off excess oil. Allow the wood to dry (thinner to evaporate) for at least 24 hrs. Scuff wood with fine scotchbrite or steel wool. Apply 2nd generous coat of Tung Oil, let soak in the for an hour or so, then wipe off excess. Set wood aside for cure, as stated above this takes time. Two proper coats are sufficient for protecting the wood.
