Product Description

The 3M 7000148239 is a gray, high-performance sprayable seam sealer designed for automotive body repair and refinishing applications. Supplied in a 10.5 fluid ounce cartridge, it can be applied by caulking gun or sprayed using a compatible applicator gun. The sealer is non-shrinking and non-cracking, cures fast, reaches tack-free in 30 minutes, and is immediately paintable after application. It adheres well to all primed surfaces except acrylic lacquer, making it a reliable general-purpose choice for structural seam work in professional body shops and collision repair environments.

This sealer is formulated for use on door skins, hemming flanges, quarter panel seams, floor pans, and trunk pans. It can also serve as a coarse-textured undercarriage coating or interior sound deadener, expanding its utility across multiple stages of a vehicle repair or restoration workflow. Extra applicator tips are included with each cartridge. The product is compatible with the Sprayable Seam Sealer Applicator Gun, part number 08400, which allows adjustment across a variety of spray patterns for flexible coverage control.
