What are the differences between the three oils? Mineral oil is the cheapest. Tung and walnut are priced about the same and both can cause alergic reactions to those that are alergic to nuts. So, I ask, what are the finishing differences. Is one better then the other (other then the cost)? Or does it just get down to a personal preference? As advertised, walnut oil will provide a hardened surface after being exposed to UVs. Mineral oil will need additional coats as it drys out. Tung oil needs to be thinned to penetrate better in the first coats. Mineral oil heated and mixed with bees wax provides a very nice seal coal. Can you do the same with walnut or tung oil or would this be counter productive. Or, if you’re going to do this, wouldn’t you be just as well off (and much cheaper) to use mineral oil and bees wax? Come on LJs, give me your thoughts, ideas, experience and or preference.
