Gehrke’s Gink has been keeping flies floating repeatedly for over 40 years. It is a liquid emulsifier that permeates deep into the body material of dry flies, and it either coats synthetics or penetrates fur or feather. Upon contact with cold water, it becomes a clear, invisible gel that keeps dry flies floating. The product has unique features and functions and has a specific gravity of 0.77%, making it lighter than water.
