That is exactly why I now use 100% Tung Oil. It dries thoroughly overnight and gives very nice results. You can also vary the gloss of the finish by using 0000 steel wool if a more satin finish is desired. If your wood needs a touch up, no need to remove the old finish, just a quick going over with the steel wool and add another coat or two. Just make sure it's 100% Tung Oil, not mixed with varnish or other chemicals. By the way, a can of Tung Oil (since it is pure) will never go bad - nothing to separate or break down.
Love the stuff! Just did my CMP M1 Carbine stock and a vintage set of S&W stocks with the stuff.
