Bohning’s Ferr-L-Tite Cool-Flex is a must have for any arrow builder. It’s designed for installing points, inserts, outserts, and pin bushings, and works great on carbon shafts but is also compatible with aluminum and fiberglass. A flame is required for application, and HOT WATER can be used for the adjustment or removal of points, inserts, outserts, and pin bushings. The Ferr-L-Tite Cool-Flex is fully cured once it reaches room temperature (about 5 minutes), and has flexible properties to prevent cracking from repeated target impacts. Made in Lake City, Michigan, U. S.A. and is available in 12-gram sticks and one-pound bricks. Bohning Ferr-L-Tite Cool-Flex 12 Gram Stick 1308
