It cures to form a permanently elastic bond, making it suitable for joints and seams that experience movement, vibration, or thermal cycling. The gray color blends well with metal and composite substrates. It adheres to a wide variety of surfaces including plastics, fiberglass-reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal, and wood. Typical installers include sheet metal fabricators, body shop technicians, marine maintenance crews, and general contractors working on enclosures, panels, or structural assemblies.\u003c\/p\u003e\u003cp\u003eThis sealant is used in applications where a flexible, durable seal is required between dissimilar materials. Common scenarios include sealing around fastener penetrations, bonding trim and panel assemblies, and waterproofing lap joints on metal or composite structures. It is well-suited to both interior and exterior applications where long-term elasticity and adhesion to mixed substrates are needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOne-component formula requires no mixing before application\u003c\/li\u003e\n\u003cli\u003eMoisture-curing system allows use in field conditions without special equipment\u003c\/li\u003e\n\u003cli\u003ePermanently elastic bond accommodates joint movement and vibration\u003c\/li\u003e\n\u003cli\u003eAdheres to plastics, FRP, SMC, aluminum, steel, coated metal, and wood\u003c\/li\u003e\n\u003cli\u003eGray color suitable for metal panel and composite assembly applications\u003c\/li\u003e\n\u003cli\u003eStandard 10.5 fluid ounce cartridge fits common caulk guns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on plastics, FRP, SMC, aluminum, steel, coated metal, and wood substrates as stated by the manufacturer.
