Dynatron™ Auto Seam Sealer Caulk is a high-adhesion solution for both bare metal and painted surfaces. While its thick consistency makes it less likely to drip, sag, or run out of a gap being sealed, it also dries quickly with little shrinkage, forming a water-tight repair that stays in place without cracking. Featuring variable application, reliable adhesion, and thick viscosity, Dynatron™ Auto Seam Sealer Caulk is perfect for fresh welds, floor seams, trunk seams, drip rails, voids, and gaps.
