At Black Gap shelter, on the Approach Trail going to Springer, a Thunderstorm blew in about 10:00pm sometime. I used a spray on silicone based application to make the flys water-REPELLANT and didn't expect a monsoon to blow in. needless to say, we got wet.
Here is a video of our explaining just what happened.
I know some have had good results with the making of their own silicone nylon, I cant seem to get the swing of it, so i will order my nylon already pregnant. with the silicone.
