SprayMax® Self-Etch & Weld-Thru Primer Aerosols – 11.2–11.3 oz

SprayMax® Self-Etch and Weld-Thru Primers are professional-grade aerosol primers designed to deliver excellent adhesion and corrosion protection on bare metal and critical surfaces. These primers chemically etch into the substrate, creating a strong bond while improving resistance to rust and moisture.

Depending on the variant, these primers can be used as a wash primer, filler primer, or weld-thru corrosion barrier, making them essential for body shops, collision repair, and fabrication work. Both formulas feature fast flash times, welding bead resistance, and compatibility with modern refinishing systems.
