Are you using pure Tung Oil? Lot of products called Tung Oil nothing more than wiping varnish or oil varnish blends. Read the label, if find petroleum distillate or mineral spirits you are not using pure Tung Oil.
Pure Tung Oil will not build a gloss finish or heavy finish. Using mineral oil will give you same results.
Neither Tung Oil nor Mineral oil penetrate, wood very much. Both take a long time to dry. Neither Tung Oil nor Mineral Oil very durable finishing material. Mineral oil cheaper than Tung Oil, and will not form a film or turn gummy in the container.
Polymerized Tung oil dries faster, but will form a film and gum up same as pure Tung Oil.
I stopped using Mineral Oil as a finish. Tried one of those Tung Oil products with chemicals added, stuff got gummy in the can. I just do not think oil products a durable finish. Yes, they have their place in woodturning. Any turning sold or given as a gift with oil as a finish should come with caveat maintenance required.
More sanding required before applying an oil product
