I have waterproofed my 10 year old riding gear and all seems to have worked well according to instructions. I have yet to ride in any heavy rain. Light rain remains as droplets on the outer parts of the jacket and pants.

As a motorcycle riding instructor, I have to stand out in the rain a lot! After a while, rain gear just loses its ability to shed rain. But one washing with Granger Wash-In Waterproofing has returned my rain gear to its original protection. (Posted on 4/23/12)
