3M Bare-Metal Seam Sealer provides excellent protection against corrosion for any and all exposed bare metal. The new beige-colored, non-sagging, fast cure-through formula can be applied directly to bare metal to match OEM seams. Bare-Metal Seam Sealer makes it easy for body shops to reproduce horizontal and vertical sealer beads, which helps increase productivity and eliminates excessive time spent duplicating original seams.
