3M™ Ultrapro 08361 1-Part Gray Economical Seam Sealer, 10.5 oz

Our 3M™ urethane seam sealer is a high solids seam sealer ideal for sealing automotive and RV seams and joints. It adheres well to bare metal, primed metal and painted surfaces and if desired can be smoothed to a featheredge and/or brushed.
