3M™ 58308 2-Part Heavy Bodied Seam Sealer, 600 mL Cartridge, Paste, Off-White/Black, 60 min Curing

Our 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. Our self-mixing system ensures a proper mix ratio every time - delivering a consistent cure rate and strength. Mixing sealer components by hand often results in a big mess and waste of materials and time. Our high-performance 3M™ heavy-bodied seam sealer operates with a two-part cartridge and nozzle that self-mixes with a perfect formulation every time and without the mess. This efficient system helps reduce application waste, improves efficiency and remains ready for job after job with no downtime for mixing mistakes. This professional-quality black 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.
