Poly, Tru Oil, Formbys Tung Oil mix, Shellac, rendered fat and bees wax all work. You will get good and bad points about each. Personal preference is what its all aboout. All will work for common "joe's" just fine. Romance plays a part for some guys. They may want all natural, or they want what the ol' timers used, or one cost more than the other and so on. The best type will never be settled. Your best bet is to simply pick one and learn about it prior to applying. Some need a fresh coat each year, or several times a year, some never need to be touched again. Some stink and some smell MMMMMM good! Warm bee's wax makes me hungry everytime!
