Simply dab a little Gehrke's Gink® onto a dry, dry fly (before it is allowed to get wet) and rub it into the fly until dressed. Hackles do not become matted or caked with Gehrke's Gink®. A serious fault of silicone based dressings that attract dirt, grit, and which cake expensive hackles into a matted mess. Gehrke's Gink® is fly friendly in all aspects.
