Well, my take is that this must be different from the origonal. This is because it is a two part spray, and, it has some disoloration when applied to fabrics. The original version was a single spray, capable of being used inside cell phones and did not cause dramatic color changes.
At any rate, it would be nice for Larry to do the testing. For me, I will wait for the origonal. It was never clear about durability, and, I am sure rain drops would cause sufficient force to penetrate the coating, I an not sure about the two coats. They are saying that it will remove breathability...usually associated with thicker coatings on nylon.
