Eliminate Mess and Downtime
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.
Match OEM Appearances
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.
Durable, Fast-Cure Formula Creates a High Quality Seal
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.
