This is a rerun of a former topic. I think it was Chuck, (or, somebody better looking) who first aimed us at Silicone Water guard ( http://www.atsko.com/products/waterproo ... guard.html ) . THIS STUFF WORKS!
However, I was unwary a few weeks ago, and got something that's on the same page of the same site - it's in the "close, but no cigar" category. ( http://www.atsko.com/products/waterproo ... guard.html ) . The BIG difference is, the wrong stuff is water based. (sound of GONG here, from the Gong Show)
I had a part of a can of the silicone stuff, and sprayed a tent until it ran out. Then I started with the water based crap. It beaded and ran off of the first spray!. And, it didn't go nearly as far per can either.
Be sure you get the real stuff, not the water based stuff.
