Thought I shared this one...
A "kumpare" of mine who is in the textile business recommended this to me. They use this to make flexible joints in their garments business. He also used this successfully to repair a carburetor diaphragm on one of their delivery trucks.
I'll look for a woofer and slash it's surround, a desperate excuse to use my new 5.11 tactical knife and test this textile glue.
