MSP Seam Sealer

3M™ Ultrapro™ MSP Seam Sealer is a premium one-part moisture-curing automotive seam sealer designed for application to exterior and interior body seams. It does not shrink and stays permanently flexible. Excellent adhesion to primed metal and aluminum means there is minimal opportunity for bond failure and fewer customer returns for seam sealer failure. Fast curing and immediately paintable means there is no need to wait to move the car into the paint area, saving time waiting to paint seam sealer. Very low solvent percentage leaves minimal airborne solvent during curing process — less orors and health issues. Excellent shelf life: Product stays usable for longer than standard seam sealers meaning less product waste.
