Description

The 3M Urethane Seam Sealer is a high-solids seam sealer designed for automotive and RV applications. It features a single-component formula that adheres well to bare metal, primed metal, and painted surfaces. This sealer is moisture-curing, providing excellent performance in high heat and humidity.

It is non-shrinking and non-cracking, remaining flexible and offering superior results compared to solvent-based sealers. The product dries quickly and is paintable within 30-45 minutes. Its thick consistency allows it to fill large voids and can be smoothed to a featheredge or brushed.
