I just literally found over at Backpackinglight http://tinyurl.com/3eqwto
a little thread about Silnet and a few guys are already using this Permatex stuff with good results. I've already sealed the exterior side of my tarp's r/l and figure I'll do the interior side too but I'm almost out of Silnet. I can get the Permatex at Ace so I'm going to try it.... unless someone chimes in with a negative review of the stuff. Oh, I didn't make my avatar. I got it from a fellow Zep Head. Long fly the Zeppelin!
