3M 08008 Black Weatherstrip Adhesive – 5 oz Tubes (2-Pack)

The 3M 08008 Black Weatherstrip Adhesive is designed to secure rubber gaskets and weatherstripping to metal surfaces, making it a practical choice for automotive seals. This adhesive is flexible and strong, drying quickly so you can move on with your project. It cures to a rubbery, resilient layer that helps maintain a tight seal around doors, trunks, sunroofs, and other joints that face daily exposure to wind, rain, and temperature shifts. Using it straight from the tube keeps the process simple and efficient, with even coverage that helps you work without lingering mess.

Key benefits at a glance

• Withstands vibration and extreme temperature variation for steady performance
• Fast-drying, strong, and flexible rubbery bond that moves with parts
• Good oil and water resistance to help protect seals in varied conditions
• Bonds to a range of surfaces including vinyl, metal, fabrics, and rubber
• Easy to brush or spread directly from the tube, saving time during application

Where you’ll notice it most

In everyday vehicle use, weatherstrip adhesion plays a role in limiting drafts, reducing wind noise, and helping keep interior moisture in check. This adhesive is suited for securing gaskets and weatherstrips at multiple points around a car’s shell—from door frames to trunk lids and sunroofs—so you can address leaks and drafts with a single, consistent product. The flexible cure adapts to movement and thermal cycling, which helps maintain a seal even as environmental conditions change between hot sun and cold nights.

• Car doors and door frames, where a reliable seal reduces drafts and wind noise
• Trunk and hood seals, to help keep out rain and road spray
• Sunroofs and panoramic vents, where movement occurs and a flexible bond matters
• Fabrics, gaskets, and metal joints common in automotive weatherstripping

How to use

Prepare surfaces by cleaning and drying to remove oils, dirt, and old sealant. Squeeze the adhesive from the tube and apply an even coat to one surface. Press the gasket or weatherstrip into place, then smooth or brush to ensure full contact. Allow the bond to cure, typically up to 24 hours, before subjecting the area to operation or stress. The result is a flexible, durable seal that adapts as parts move with temperature and vibration.

Tips for best results

• Apply in a well-ventilated area and wear gloves to protect skin
• For thicker joints, apply in stages and allow initial tack to set before final positioning
• Avoid squeezing excess adhesive beyond the seam to minimize cleanup
• Check cure time and avoid heavy use until full cure is achieved
