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.
Using the Seam Sealer Effectively
Our 3M™ Heavy-Bodied Seam Sealer for DMS (PN 58308) comes in a kit that includes a 600 mL cartridge, two “purple” mixing nozzles (PN 55847, also available in boxes) and an extension tube for attaching an OEM tip to the mixing nozzle. The 600 mL cartridges fit into our 3M™ Dynamic Mixing Applicator – Pneumatic (PN 05846).

About DMS, a Self-Mixing System
Our 3M™ Dynamic Mixing System (DMS) increases job productivity while ensuring the body repair quality you’ve come to expect from 3M. With the Dynamic Mixing System, you dispense fillers, glazes, adhesives, sealers and plastic repair products when and where you want them, at the touch of a trigger. There is no messy mixing process, no wasted materials, and no lost time cleaning up. By utilizing the correct amount of product and reducing consumption, you save both materials and time.
3M Science Meets the Needs of Automotive Professionals
3M used science to create a sealer that combines toughness with flexibility. 3M™ Heavy-Bodied Seam Sealer is ideal for lasting seam sealing protection on many different surfaces, and allows technicians to expertly recreate OEM seam sealer appearances. This formula, along with the self-mixing 3M™ Dynamic Mixing System, represents another way that 3M applies science to improve working conditions and productivity in the automotive industry.
