Ruth sent us a good question: I have 50 year old oak floors that need to be refinished. I've done some research and am very interested in using old-fashioned (and green!) tung oil rather than the lacquers that are the current norm. Have you used tung oil on your floors? What was your experience with the refinishing and maintenance process? It all sounds too good to be true with easy repair of scratches and marks, water resistance and durability!!
