High Teck 7422-4 2K High Build & Sealer Buff Urethane Primer is a two-component urethane primer designed for professional collision repair applications requiring superior build and excellent sanding characteristics.

Mixed at a 4:1 ratio, this zero VOC formula provides exceptional adhesion across multiple substrates including bare metal, e-coat, plastic, and existing primer surfaces. The high-build properties deliver efficient coverage while maintaining excellent sandability for smooth surface preparation.
