Product Description

3M 08369 MSP Medium Bodied Seam Sealer (White, 310mL) is a professional-grade automotive seam sealer engineered for structural and cosmetic seam sealing in collision repair. Heavy-bodied, non-sag formula maintains its shape on vertical and overhead seams — door jambs, pillar seams, wheel well lips, and any joint requiring a bead that stays where placed during cure.

MSP chemistry provides superior long-term adhesion to bare metal, e-coated, primed, and painted substrates with the flexibility to resist cracking from panel vibration and thermal cycling throughout the vehicle's service life. White-colored formula matches common OEM seam seal color profiles for a factory-appearance repair. Paintable after proper flash time — finish with any topcoat system.
