Description

The 3M Heavy-Bodied Seam Sealer is a two-part epoxy designed for general-purpose automotive sealing applications. It quickly cures to form a tough, strong bead, providing lasting protection for seams.

This sealer is suitable for use on door skins, floor pans, trunk floors, roof seams, and other body applications. Its self-mixing system in a dual cartridge ensures a consistent mix ratio and cure rate without mess.
