Clear Cure Goo's thinnest material, tack-free Hydro cures in just five seconds. Because it has the consistency of watery head cement, it can be used as a top coat for any of the Clear Cure Goo materials. Adds durability to delicate flies and a lifelike translucency. Saltwater fly tiers can use the Hydro to stiffen materials. Make a fly solely out of Hydro without any need for head cement or lacquer by applying a little at a time, curing as you go. Eliminates the need for any alcohol for tack-free results. Includes applicator top, brush top, fine applicator tip and extra-fine applicator tip. Curing time: 5-10 seconds. Size: 15ml bottle.
