SOF UV Curable Fly-Fishing Adhesive Kit is field tested by the staff of Seasons on the Fly for use on all types of fly tying. This kit includes: one 10ml bottle of thin adhesive, one 10ml bottle of thick adhesive, and a UV-curing flashlight. These are excellent adhesives for bonding most natural and synthetic materials. Adhesives will not cure until exposed to UV light or direct sunlight; and they do not soften or whiten when exposed to water. Thin glue is ideal for wicking into materials for a light layer of adhesive. Thick glue can be layered on, to create a build-up on insect eyes and bodies, as well as realistic bug shells on beetles and ants. The UV-curing flashlight produces an adjustable, high-intensity LED beam; and is water resistant.
