A Strong Adhesion Seam Sealer
3M™ MSP Seam Sealer adheres exceptionally well to bare metal, primed and painted surfaces. Our high quality, heavy-bodied and moisture-curing seam sealer may be used on both interior and exterior body joints. It dries to be tack free in 30 minutes and is immediately paintable up to 72 hours without abrading. Our seam sealer offers the convenience of being a one-part formula that does not shrink and stays permanently flexible. This seam sealer is not recommended for acrylic lacquer surfaces.
Better Results for Professional Auto Body Shops
When your reputation as an automotive body shop that does quality work is on the line, you want to use a seam sealer that is proven for reliability. Excellent adhesion to primed metal and aluminum means there is minimal opportunity for bond failure and fewer customer returns for seam sealer failure. With its fast curing properties, our seam sealer boosts auto shop productivity.
A User-Friendly Product for Automotive Technicians
Our seam sealer has been formulated so that it is more pleasant and easier to use. Its low solvent percentage means there is less airborne solvent during curing process and less odor. This seam sealer has an excellent shelf life and generally stays usable longer than standard seam sealers, resulting in less product waste.
Recommended Applicator Gun
We recommend applying 3M™ MSP Seam Sealer with our 3M™ Flexible Package Applicator Gun, 08398 (sold separately). This fully enclosed, all metal, rod driven, friction feed applicator gun smoothly and effortlessly dispenses single component products packaged in 310 mL and smaller flex packs.
