Works pretty well

I used this spray on a backpack and a large brimmed hat. They were not new and I washed them first with soap and water by hand. I then applied two coats to both, letting them dry between coats. At the end, they worked a bit better than before, but the water did not really bead up so much as sit on the surface and not get sucked in. I took them to Peru and was rained on almost every day, but the pack seemed to keep the water out fine, although the hat seemed pretty much unchanged from before treatment, ie, it got damp but not wet.
