The Roman Moser Miracle Fly Floatant is a synthetic fly grease with a very low melting point. Rub a droplet between your fingers until liquid and work into the fly. The grease creates a thin wax like protection film and the fly will float high with this long lasting floatant. Even when drowned the fly appears again like a cork on the water surface. Also suitable for CDC Flies and floating leaders. USE SPARINGLY.
