The choice between zinc and copper weld-through primer depends on specific needs. Zinc weld-through primer offers excellent corrosion resistance and is commonly used for its protective qualities of bare metal before and after welding. Copper weld-through primer, on the other hand, provides superior conductivity, making it better suited for applications requiring high electrical conductivity, such as certain automotive Resistance Spot, MIG and TIG welding repairs.
