UV Clear Fly Finish by Loon Outdoors is for those who believe five minutes to cure is five minutes too long. No mixing or waiting is required, and it remains workable until exposed to direct sunlight or Loon's UV Bench Light or UV Infiniti Light, at which point it will cure in a matter of seconds. The possibilities are endless! Thick ½ oz. includes 2 tips and an applicator brush. Thin ½ oz. includes 2 tips and an applicator brush, with less viscosity than the original. UV Clear Fly Finish Thin is perfect for delicate applications, going on thin without sacrificing curing speed and strength. It can be used to make smaller heads, bodies, or wing cases, or to coat a small thread head. Flow ½ oz. includes two tips and an applicator brush. The thinnest UV resin available from Loon, Flow is thin enough to work as a head cement replacement, but strong enough to coat heads, bodies, and midges. Cures within seconds when exposed to Loon's UV Bench Light or UV Infiniti Light.
