Wapsi Flex-Seal Cement

Flex-Seal stands out as one of the most adaptable head cements for fly tying. This clear, rubber-based formula penetrates deeply and dries rapidly. Once cured, it forms a durable, rubbery coating. Essentially, Flex-Seal functions simultaneously as a sealant, adhesive, and head cement, making it an all-in-one solution for fly tyers.
