I've used Formby's Tung Oil for years mainly because of it's drying time. The stores selling it are becoming scare and I have had to order it on line. I have mixed danish oil and polyurethane together and it builds well, but takes overnight to dry. My question is has anyone had experience using Japan dryer to accelerate the drying time. I know it is used in oil based paint so it should work, and understand it will give more amber color to the finish. What does the dryer do to shelf life? How much dryer/oil/ poly works well? Which oils are best, boiled linseed, so called tung or other?
