Loon Outdoors Uv Knot Sense
Smooths and strengthens your knots immediately. Lightly coat those newly tied nail knots and never get caught in your guides again. Great for repairing damaged flies. Apply in full shade or inside, then let the adhesive cure in full, direct sunlight or under one of Loon's UV lamps. Will not cure indoors, even through a window. 1/2 oz. tube with nozzle top.
