I found that citrus solvent & Tung oil by mistake I built a wooden counter top for our kitchen & my wife was doing research on food safe finishes & found it as a food safe water repellent finish ,I have used tung oil on many peaces of furniture but this citrus solvent tung oil seems to penetrate a lot deeper you get a slightly darker color in the wood because of the deeper penetration , I'm going to use it as a finish on the osage bow I'm working on now & see how it works out , it was originaly designed as a natural flooring finish , so I figure if it was designed to be walked on all day it would work for other wood products.
