Duramix High-Build Self-Leveling Seam Sealer (7 oz)

Seymour Duramix™ Automotive High-Build Self-Leveling Seam Sealer Product Details

Seymour Duramix™ High-Build Self-Leveling Seam Sealer is a 2K seam sealer designed for horizontal automotive seams that need controlled flow and an OEM appearance.

It’s excellent for professional collision repair and restoration work on drip rails, trunks, roof seams, and quarter panel-to-rear deck seams. Our high-build formula levels into the seam and helps duplicate the appearance of OEM seam sealers on properly prepared substrates.

With 20 to 30 minutes of working time, our automotive high-build self-leveling seam sealer gives technicians time for proper placement before cure. It’s sandable and paintable in 60 minutes to help keep repair and refinishing work moving.

Controlled Flow for Horizontal Seam Applications

Some repairs call for a standard bead. Others need a seam sealer that can settle into the joint and build a clean, level seam that matches the original. That’s where Duramix™ High-Build performs best.

Use it where the repair requires a controlled flow, high build, and a finished appearance that closely matches the original seam.

• For vertical seams or bead-style applications, use the appropriate Duramix™ seam sealer based on the repair procedure and desired appearance.
