Flex Seal

Stiffen materials such as turkey quills when used in hopper wings and nymph casings without making them overly stiff. A sealant, Flex Seal makes feathers, deer hair, and similar materials more durable. When dry it produces an extremely tough “rubber like” finish. A good way to describe Flex-Seal is to say it is a sealant, adhesive, and head cement all wrapped up into one product.
