Product Summary

J-B Weld Clear RTV Silicone Sealant Adhesive is a versatile, general-purpose sealant designed for both household and automotive use. This 3 oz tube delivers a clear, flexible silicone that cures at room temperature (RTV), forming a durable, waterproof seal resistant to mildew, mold, and weathering. It bonds securely to a wide variety of surfaces including plastic, composite materials, PVC, glass, wood, fiberglass, and tile. The sealant cures by reacting with moisture in the air, setting in just one hour, and remains flexible without shrinking or cracking. Ideal for sealing wet or underwater surfaces and sensor-safe, it’s perfect for mechanical assembly, repairs, and DIY projects that demand a clear, long-lasting seal.
