If you own a sil-nylon tent, SilNet is a must-have (unless you like sleeping in puddles). That's because Sil-nylon tents are not sealed at the factory. Stay dry! Use SilNet to seal the seams on your silicone-treated tent, tarp, backpack and rain-wear. Use it to repair pinholes, too. SilNet is part of a comprehensive line of Care and Repair products from Gear Aid. With Gear Aid, anyone can be a master of gear repair. The only seam sealer ideal for sil-nylon fabrics.
