Perfect for tying flies and gluing hooks into bodies. A super glue from the maker of Zap products, Wapsi Fly Tyers Z-Ment has a special formula made for fly tying. This cement is low viscosity to penetrate tying materials, dries in 10 to 15 seconds and makes flies 'bomb-proof'. The 1/2 oz. bottle has a brush-on applicator top.
