3M 08308 - Heavy Bodied Seam Sealer (200mL)

3M 08308 Heavy Bodied Seam Sealer (200 mL) is a professional-grade automotive seam sealer designed to replicate OEM-style seams in collision repair and restoration applications. This heavy-bodied formula is ideal for vertical and irregular surfaces where a thicker, non-sag consistency is required to maintain bead shape and texture.

Formulated for use on primed or properly prepared metal surfaces, the sealer helps protect panel joints from moisture intrusion and corrosion. The 200 mL cartridge is compatible with standard applicator guns and is commonly used for door skins, quarter panels, trunk seams, wheel housings, and other body panel joints in automotive refinishing environments.
