Gehrke’s ® is now 28 years old. It is the first commercially offered, safe, dry fly dressing that floated flies repeatedly. Its' features and functions are unique in the world of chemistry and fly fishing. Gehrke’s ® has a specific gravity of only .77% that of water, which means it's lighter than water. Gehrke’s ® is a liquid emulsifier that permeates deep into the body material of dry flies. It will either coat sythetics or penetrate fur or feather.
® 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.
