3M Heavy-Bodied Seam Sealer 08308 & 58308

3M Heavy-Bodied Seam Sealer lays down a thick, non-sag bead that holds its shape on vertical and overhead seams, so collision techs can tool it to match factory seam patterns. It fills wide gaps, can be painted once cured, and helps keep water and dust out of repaired joints. Choose 200 mL cartridges or 600 mL DMS cartridges. See Bare-Metal Seam Sealer for sealing directly on bare metal.
