Our sealer creates a water-tight repair that stay in place without cracking. Recommended applications include fresh welds, floor seams, trunk seams, drip rails, voids and gaps.
Easy to Use with Fast Results
Our seam sealer formula can be brushed or painted on with exceptionally high quality results. When desired, it can be feathered out to a thin layer. The sealer starts to skin in about 10 to 15 minutes and should be fully hard by the next day.
