Gink is a light paste that turns to a liquid at skin temperature. Upon coming in contact with cold water it returns to a clear, unseen, invisible gel that keeps water from making your dry flies or streaking streamers, wet. Flies stay dry for the normal useful life of any and all dry flies astream. The product will even float a bare #8 light wire dry fly hook, but this is nothing more than an entertaining thing to see float in a glass of water. Simply rinse the fly after a fish is caught and false cast dry. Dress only the first two inches of tippet from dry flies with Gink as this is all the leader necessary to float from the fly.
