The LAUCO Zinc Coat Weld-Thru Primer is a high-performance, zinc-rich coating designed to protect metal surfaces during and after welding. Engineered for professional use, it provides superior corrosion resistance while maintaining excellent conductivity for welding applications.

This advanced formula allows you to weld directly through the coating without compromising bond strength or weld quality. It helps minimize weld spatter and reduces the heat-affected zone, resulting in cleaner and more precise welds.

With its strong adhesion to bare metal, this primer forms a durable protective layer that prevents rust and corrosion, even in hard-to-reach areas between welded surfaces. It is ideal for use in automotive body repairs, metal fabrication, restoration projects, and industrial environments.

The fast-drying aerosol application ensures easy use and efficient workflow, allowing you to complete projects faster without sacrificing performance. Whether you're working with MIG welding or spot welding, this weld-thru primer delivers reliable, professional-grade results.

Packaged in a 15.5 oz (440g) can, LAUCO Zinc Coat is the ideal solution for protecting metal surfaces before welding while ensuring long-term durability and corrosion resistance.
