Product Introduction
3M™ Bare Metal Seam Sealer is a two-part epoxy sealing material designed to create a tough, flexible seal on bare metal joints, including steel and aluminum, as well as primed or painted metal surfaces used in collision repair. This self-mixing epoxy sealer can be easily caulked, tooled, or brushed into seams, providing an efficient sealing solution that cures in as little as 15 minutes. Its neutral beige color reduces painting time and material usage by minimizing the number of paint coats needed.
Formulated to deliver long-lasting performance, 3M™ Bare Metal Seam Sealer forms a durable, non-shrinking, non-cracking, and non-outgassing seal. Its heavy-bodied, non-sagging formulation ensures clean and efficient application on both vertical and horizontal seams, helping to recreate original equipment manufacturer (OEM) seam appearances. Additionally, it contains chemical corrosion inhibitors to protect against rust and supports a variety of application methods using 3M™ OEM Seam Sealer Tips. The dual-syringe cartridge system ensures accurate self-mixing for consistent strength and cure speed.
