J-B Weld 31316 Blue RTV Silicone Gasket Maker & Sealant, 3-oz

JB Weld Silicone Sealant is a handy product for sealing and bonding uneven surfaces around the house or garage. The RTV silicone adhesive simply requires exposure to air moisture to cure into a tough, waterproof seal on most surfaces. It won't shrink or crack over time and is perfect for sealing automotive accessories and household applications where a long-lasting, weather-resistant seal is needed.
