This stuff's been around forever, and for good reason too! Just rub a small dab of George Gehrke's silicone-based Gink Fly Floatant into your dry fly hackles or hairwings prior to casting, and watch them bob and float on the water's surface like corks! A must not only for dry flies, but for gaudy deer hair bass bugs, bushy salmon bombers, and much more, if you want to it float high and long, you best treat your fly with Gink!
