Tung oil is my favorite finish on almost any wood project. As I said for a cane or stick I want to be special I use !00% tung oil or marine tung oil. The are more work and drying time can very a lot depending on humidity and temperature. The higher grade tung oils are expensive. I do not use them all the time. It will darken you wood and it can darken more over time.I've also thinned with 50/50 min spirits or paint thinner on spar.
I hate to sound like a broken record but have any of you guys tried putting the tung oil finishes on your sticks, waiting as per instructions then burnishing it at a rate of speed with say a paper bag instead of wiping oil off with a cloth? I'm quite happy with the shine it gives and it dries fast. All of about 3 coats is all you need.
