Seasons on the Fly 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 formulas 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 buildup on insect eyes and bodies, as well as realistic bug shells on beetles and ants. The water-resistant, UV-curing flashlight produces an adjustable, high-intensity LED beam. Cancer and Reproductive Harm- www.P65Warnings.ca.gov.
