I was watching a hunting show and Bob Foulkrod actually mixes a tube of clear silicone with odorless paint thinner and brushes it on his pop up hunting blinds. I wondered if any of you had tried this. He claims it seals the blind better than any sprays and works great. I googled it and it is on a few DIY videos for tent seams. I wonder if the aqua seal I use on my neoprene waders is basically the same mixture in a tube. I've used camp dry and it's an ongoing application where this is more one and done in theory.
