Planeman…I don’t know where you’re getting your information, but pure tung oil polymerizes in the presence of oxygen, forming a relatively hard film. What do you mean by wax?

Heat and chemically processed tung oil like Waterlox, which is mixed with resins, solvents, and driers, will gel in the container, but pure tung oil won’t.
