Paintable When Dry

The 3M Brushable Seam Sealer Gray is a specially developed product that can be used for sealing floor pans, firewalls, trunk seams, shock absorber mounting towers around wheel wells, fuel filler splash pans and around headlight and taillight openings. It seals sheet metal overlap joints that have been spot welded, riveted or bolted together. 

This sealer dries quickly without sag or flow, to restore factory appearance, and can be painted when dry. It adheres to primed or painted surfaces and remains flexible while resisting oil, fuel, and other automotive fluids. It applies easily with a brush.

The 3M Brushable Seam Sealer Gray holds brush marks well. It can be used even in engine compartments since it is oil and fuel resistant. To use this product on various automobile seams, lightly scuff the area to be sealed. Then, clean it with soap and water. After the surface dries, clean it with a 3M VOC compliant product.
