3M™ 08362 1-Component Seam Sealer

3M urethane seam sealer delivers professional-grade protection for automotive and RV joints. This single-component formula bonds to bare, primed, and painted metal surfaces while remaining permanently flexible. It cures tack-free in 30-45 minutes and is paintable, with no shrinking, cracking, or odor. The thick consistency fills large gaps effectively and resists water, dust, and corrosion. Ideal for interior and exterior seams.
