Been using it for our wetsuits, neoprene gloves and booties for over 10 years. Patches holes, tears and making more comfortable knee padding. Dries in one day, not sure why they even make the 7 day cure adhesive. In the pictures the more worn gloves were coated with 3m last year, and probably been used about 3 months of actual use in the water. And we're not easy on gloves, always hand raking gravel.
There is no adhesive on the planet that can compare to it no matter what you use it for. Beware...once you apply it you cannot separate it, it's permanent.
