Provides a permanent waterproof coating on flies, materials, dubbing, yarns, and even nylon leaders. It does not affect the colour or softness of the material it is applied to and it is completely odourless after drying. It can be applied directly or dabbed on with fingers. One drop is all that is needed.

It must be applied at least 24 hours before fishing and must not be used on wet material as it will not cure.   An amazing waterproofing agent.
