The Tuffleye Advantage
Tuffleye is a new product offered by Wet A Hook, Tuffleye isn't a replacement for epoxy; it's better than epoxy. Epoxy cures due to a chemical reaction between the resin and hardener. Tuffleye, however, is a light-cured clear acrylic that doesn't harden until you bathe it in a specific blue light. With Tuffleye you have all the time in the world to shape and smooth the material before you turn on the light and cure the material.
There are several advantages to using Tuffleye. First, there is no waste: simply squeeze out the exact amount you wish to use onto the fly, and then draw back the syringe plunger to pull any excess material back into the tube. Second, Tuffleye doesn't yellow the way epoxy can. And finally, there's no worrying about thoroughly mixing epoxy; Tuffleye will always cure to a hard, strong finish.
Tuffleye is the perfect substitute for epoxy for tying flies. Use it for fashioning heads, wing cases, and other parts, or for gluing on rattles and eyes, Tuffleye is one of the best innovations in fly-tying material in years.
