The Science and the Art of 3M Sealers and Coatings

3M seam sealers and coatings are scientifically developed to be simultaneously tough and flexible for long-lasting performance. They range from brushable to sprayable, so you can more easily match OEM appearance in collision repair. You’ll find a sealer for virtually any application – urethane and epoxy sealers and convenient strip and ribbon sealers are just a few. Our selection of coatings includes undercoats, anti-chip coatings and corrosion protection. 3M also offers related products such as applicator guns and metered static mixing cartridges.
