I don't know, but you could always be the brave one and try. I would not risk screwing up my gallon of working XT-3R by trying, but feel free K-G.I have used X-tol replenished for several years with good result and also tried XT-3 at 1+1 dilution, also with good result. Does anyone know if XT-3 is so similar to X-tol that you can replenish an old X-tol solution with new XT-3 solution ?
