3M™ Heavy-Bodied Seam Sealer, 08308, 200 mL Cartridge, 6 per case

The 3M™ Heavy-Bodied Seam Sealer is a two-part epoxy seam sealer for all general purpose automotive sealing. It cures quickly to a tough, strong bead for lasting seam sealing protection and is used on door skins, floor pans, trunk floors, roof seams, and many other applications. The self-mixing system ensures a proper mix ratio every time - delivering a consistent cure rate and strength.

This black 3M™ Heavy-Bodied Seam Sealer seam sealer can be used to seal vertical or horizontal seams on automotive surfaces primed with a 2K urethane, 2K epoxy primer, or clean, sanded paint. Its non-flowing, heavy-bodied formula allows technicians to texturize the seam to match OEM seam sealer appearances and duplicate OEM beads. Our flexible formula works within a wide range of temperatures with no shrinking or cracking to achieve strong, durable construction. It offers a fast setup time of 6 minutes, decreasing downtime and allowing technicians to continue repair procedures quicker, increasing productivity. Moreover, the fast-cure formula means there is a limited time of uncured product on the car and the risk of damaging the seam by disturbing uncured seam sealer is greatly reduced. This enables technicians to quickly achieve a long-lasting, high quality seam seal. Our high-performance 3M™ Heavy-Bodied Seam Sealer operates with a two-part cartridge and nozzle that self-mixes the material. This efficient system helps reduce application waste, improves efficiency, and remains ready for job after job with no downtime for mixing mistakes. Combine with 3M™ OEM Seam Sealer Tips to recreate various OEM seam shapes.
