When using a silcone/nylon tent, the best way to keep moisture out is to use Seam Grip SIL. 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. Only silicone adheres to silicone so this is a must if you’re waterproofing a silnylon tent.
