Duplicates OEM Sealer Appearance

Here’s one of the strongest sealants available for general sealing of various vehicle parts: 3M Automix Heavy-Bodied Seam Sealer. The two-part epoxy-based seam sealer is perfect for door skins, floor pans, trunk floors, roof seams, and more.

One of the most important features of this sealer is its quick curing time, which reduces the time taken to complete projects; the quick cure does not reduce the product’s sealing quality. It features a self-mixing system that provides perfectly proportioned sealant every time. It also has a non-sagging paste-like texture that does not flow, ensuring clean work. 

The quick cure time reduces the time to complete a project and increase productivity in your body shop. Increased productivity directly translates to more work done and eventually more revenue. The product can be used in different temperature settings too and does not restrict its usage if the weather becomes too hot or too cold.

The extremely flexible epoxy mixture is strong and durable, thus ensuring the longevity of the sealing work. 3M Automix Heavy-Bodied Seam Sealer is of such high quality that it can easily duplicate the original equipment manufacturer (OEM) sealer quality and appearance.

Special Features of the 3M Automix Heavy-Bodied Seam Sealer

  • Strong bead for long lasting seal
  • Non-sagging, paste-like texture that does not flow
  • Fast curing time

Important Points to Remember:

  • Do not bring acid etch primers in direct contact with seam sealer
  • Scuff the primed surface with a Scotch-Brite™ General Purpose Hand Pad (Ultrafine)
  • Blow off any remaining dust with clean, compressed air and wipe with a dry rag before applying the sealer
