Gasket Maker & Sealer JB Weld 3 oz Blue RTV Silicone

JB Weld blue silicone gasket maker and silicone is an RTV (room temperature vulcanized) silicone designed for use in mechanical assemblies, sealing and bonding uneven surfaces. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof seal on most surfaces. Cures to a blue color. Will not shrink or crack, resists weathering, is sensor safe and is great for many automotive applications. Great for timing gear covers, transmission pans, oil pans, water pumps, valve covers, differential covers, and thermostat housings.
