I just discovered this stuff. Widely available, under a variety of brands (and prices!), also known as self amalgamating silicone tape.
Does anybody know if this will bond with the silicone coating on waterproof fabrics?
I’ve only seen it in 20mil thickness x 1″ wide, which is about 3x heavier than seam sealer. If it works, and can be found thinner and narrower, this could be an awesome diy seam tape.
