Seam sealing with Seam Grip SIL is the best way to keep moisture out when using a silnylon (silicone-nylon) tent. Previously known as SilNet, this clear sealant dries to a flexible rubber that works on all silicone treated gear including nylon tarps and ultralight backpacks. 

• Bonds to silicone treated fabrics to prevent water from seeping through seams
• Provides a water-tight seal that won’t peel or crack over time
• Rubber sealant seals seams and patches leaks for repairs that last for years
• Cures to an elastic, rubber seal that flexes and stretches
