3M 08609 Super Fast Urethane, 10.5OZ

3M 08609 Windo-Weld™ Super Fast Urethane is a one-part, moisture-curing polyurethane adhesive designed to securely bond replacement auto glass—including windshields, backlites, and sidelites—to vehicle bodies. This medium-viscosity, paste-style urethane comes in a 10.5 fl oz (310 mL) cartridge and requires no mixing, making it especially convenient for mobile or on-site glass replacements. It offers a 10–20 minute work/handling window, helps prevent leaks and water intrusion when properly applied, and reaches full cure in 24 hours.
