Perfect for delicate applications, Loon Outdoors UV Clear Thin Fly Finish has less viscosity than the original finish to create smaller heads, bodies or wing cases and coat small thread heads without excess. Apply the finish using the included brush or needle-tip applicator and expose it to UV light, using either a lamp or sunlight, and it hardens within approximately 15 seconds. Taper-tip, UV-blocking application needle prevents clogs. Apply while indoors or shaded from sun. 0.5-oz. bottle. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Glue.
