Tung oil is all I use and it makes for a great finish and is very forgiving. It can yellow a tad over time though, but you need a good eye to notice it. I put a coat of paste wax (Johnson's Floor Wax or similar) on the dried tung oil and buff it out.
I wood burn my sticks and you have to be careful of the wax getting into the crevices or it will turn white if not buffed out.
I use tung oil on all my wood projects that need a finish. 3 coats gives perfect depth, for my wood works.
I also do wood burning (pyrography) and also finish it with tung oil. I did some experiments wood burning on various woods with different finishes and, and the tung oil held up the best over long direct sun exposures. Good stuff.
