Loon's Clear Fly Finish puts a protective clear coating on heads and bodies and repairs damaged flies. Now available in three levels of viscosity. All formulas give you infinite work time indoors, are equally strong, and cure hard and tack free - quickly in sunlight or instantly with the Loon Outdoors UV power light or Mega Light. Applicator needles are included for fine detailed work. Larger 2 oz. (59 ml) sizes offer improved value. The 1/2 oz. (15 ml) size is offered for light usage, limited budgets and travel. Loon Fluorescing UV Clear Fly Finish performs just like UV Clear Fly Finish Flow, and takes the UV light that is available underwater and reflect it as a color more visible to fish.
