A Durable Bond Where it Matters Most You take your auto weatherstripping for granted – until it starts to fail. 3M Black Super Weatherstrip Adhesive is designed specifically to bond seals and gaskets to metal, ideal for helping ensure a waterproof, airtight seal inside your vehicle. Preferred by auto professionals for decades, this adhesive was developed by 3M to bond with weatherstripping around doors, trunks, T-tops and sun roofs as well as around your windows. It bonds permanently to a large variety of surfaces including rubber, fabrics, gaskets, seals and metal. The weatherstripping adhesive is very easy to use. Simply squeeze it right from the tube, easily brush and spread as needed on each surface, and let it cure for up to 24 hours. The adhesive remains flexible, yet it resists nearly any condition you’re likely to encounter in your vehicle – wind, rain, vibration, temperature changes, detergents, grease and more.
