Gink Floatant

Gink Floatant keeps your fly floating on the surface. It comes in a handy dispenser and works well in cold weather. 
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.
Gink Floatant is one of the most popular fly floatants around.
