WindWalker, Read some of Jay Massey's books, if you already haven't. He spent lots of time hunting Alaska and in all conditions. You might get some insight into caring for wood bows in the extremes Alaskan environment. Jay used mostly sinew backed osage bows and one of his last, Medicine Bow, was sinew backed hickory. In the end, Jay used "Massey" finish; epoxy thinned with a solvent but early on he used French polish; linseed oil and shellac mixture, hand rubbed in multiple applications. Pat
