We tested this floatant extensively and just had to add it to our product line. This is an amazing silicone-free dry fly treatment. It comes in a convenient .25 OZ. container for easy use on the water. Works on all dry fly, leader and tippet material. It takes very little to keep your dry fly buoyant for extended periods on the water. Simply apply a very small amount between your fingers and then rub it into the hackle and fly body. Use it very sparingly to avoid matting down your hackle. However if you do don't worry. Simply blow on the fly to restore the hackle to its original condition! Apply equally sparingly on your tippet and furled lines as well. A little goes a long ways!
