McNett Silicone Tent Sealant, formerly known as Silnet. A silicone-based seam sealer for use on silicone treated fabrics. It’s fast and easy to use. The silicone adhesive in Silnet waterproofs tent seams with just one application. Silnet’s exclusive formula is not affected by extreme heat or cold. Plus, it comes in handy for repairs on moderate rips and tears.

Regular adhesives and seam sealers are unlikely to work on silicone treated fabrics.
