Raw Tung Oil dries faster than BLO when applied properly.
Polymerized Tung Oil dries even faster.
Metallic driers have little or no effect on Tung Oil and are seldom used by manufacturers.

Polymerized tung oil (PTO) dries to a glossier finish than raw tung oil, but still needs to be applied in very thin coats with 3 – 4 days (or more) drying time between coats. The emphasis is on VERY THIN coats of PTO and adequate drying time between coats. The first coat is the most critical. I dilute the PTO about 50/50 with mineral spirits and apply it, then wipe off the excess after about 20 minutes. If it is still wet, then I wipe it again. I allow the first coat to dry and cure for about a week.

Avoid using Pledge Orange Oil. While it contains some D-Limonene (so-called Orange Oil), it also contains Silicone Oil which can play havoc with any future refinishing attempts. It’s mostly made of Mineral Oil and it never dries. Consider using a good furniture-grade paste wax.
