3M Bare-Metal Seam Sealer 08310 & 58310

3M Bare-Metal Seam Sealer goes directly onto bare steel and aluminum in collision repair, sealing replacement panel seams without a separate primer while helping guard the joint against corrosion. The beige sealer can be tooled to match factory seams and painted once cured. Choose 200 mL cartridges or 600 mL cartridges for 3M’s Dynamic Mixing System. See Panel Bonding Adhesive for bonding the panels themselves.
