Versatile Seam Sealer
Dynatron™ Auto Seam Sealer Caulk lay down well on both bare metal and painted surfaces. Our sealer offers high adhesion and has a thick consistency that makes it less likely to drip, sag or run out of the gap being sealed. It dries quickly with little shrinkage. 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.
