A Tough, Durable Seam Sealer…
Our 3M™ Bare Metal Seam Sealer forms a durable seal to overlapping sheet metal with no shrinkage, cracking or outgassing – and lets you apply it efficiently and cost effectively. The heavy bodied sealer is formulated specifically to adhere consistently to properly prepared bare metal, such as steel or aluminum enclosures, in collision repair. It is non sagging and non flowing, making it easy to apply and tool to shape, for the most effective seal and to recreate the OEM seal appearance. It also contains chemical corrosion inhibitors to help prevent rust. This sealer cures in as little as 15 minutes for efficient shop time, and is fully paintable using any automotive paint system. Its neutral beige color can make painting easier and require fewer coats vs. a darker colored sealer.
That’s Also Easy to Use
This sealer dispenses from a dual syringe cartridge – it accurately self mixes to deliver the strength and adhesion of a two part epoxy system without the added time and guesswork of mixing. You get the right mix ratio for individual jobs, and consistent strength and cure speed every time. 3M™ Bare Metal Seam Sealer can be caulked with 3M™ OEM Seam Sealer Tips including 08201, 08202, 08203, 08204 and 08205. It can also be used effectively on primed or painted metal surfaces.
