J-B Weld 32329 Ultimate Black Gasket Maker & Sealant, 3-oz

JB Weld Ultimate Black Gasket Maker & Sealant is an RTV (room temperature vulcanized) silicone gasket material designed for use in mechanical assemblies where maximum petroleum and oil resistance is required. Upon curing, which occurs when the product is exposed to moisture in the air, the silicone forms a strong, waterproof gasket and seal on most surfaces. It does not shrink or crack, resists oil and petroleum products, is weather resistant, sensor safe, has good temperature resistance up to 500 F intermittent, and is ideal for many automotive applications.
