Part #: 1370

The seymour - duramix 1370 Heavy Bodied Seam Sealer in Beige is engineered for professional automotive and industrial applications requiring a robust, durable seal. This high-performance sealant is formulated to provide excellent adhesion and flexibility, ensuring long-lasting protection against moisture, dust, and corrosion in critical joints and seams.

  • Non-Sag Formula: Maintains its shape and position, allowing for precise application on vertical surfaces and overhead seams without dripping or slumping.
  • Flexible and Durable: Cures to a tough yet flexible seal that resists cracking and shrinking, accommodating minor movements and vibrations common in vehicle bodies and industrial equipment.
  • Corrosion and Water Resistance: Effectively seals out moisture and corrosive elements, protecting underlying materials and extending service life.
  • Paintable Finish: Can be painted over once cured, allowing for seamless integration with existing finishes and aesthetic requirements.
  • Beige Color: Provides a neutral finish that blends well with a range of common automotive and industrial interiors or can be easily top-coated.
