It’s the hot-melt stick cement used by generations of rodmakers for sticking ferrules where they should be stuck. Ideal for restoration work, and some makers prefer it for new construction, too. This stuff has high tensile strength, and it produces a tough, elastic, waterproof bond. Unlike epoxy, this can easily be removed at a later date if you need to change fittings. Don’t confuse this specialty rodmaking adhesive with the brittle adhesive that accompanies a hot-melt glue gun; the latter won’t stand up to the stress of casting. Ferr-L-Tite Cement belongs in everyone’s travel repair kit. Use it to re-stick ferrules, tip tops, & reel seats. Ferr-L-Tite Cement is the duct tape of the angling profession. Get some.
