SprayMax 1K Self Etch Weld‑Thru Primer in Red Brown is a single‑component, high‑solids primer designed for weld‑through applications on automotive panels. It provides immediate corrosion protection and a uniform base coat before final topcoat, making it ideal for repair and new‑build body shop projects.
The primer offers a flash time of 2–3 minutes, enabling rapid handling and efficient workflow. With a VOC rating of 0 % and compatibility with a wide range of substrates—including aluminum, e‑coat, galvanized steel, plastic, polyester, existing primers, and steel—it delivers consistent adhesion and coverage across diverse repair scenarios.
Because the formulation contains acute toxicity, carcinogenic, and flammable components, proper PPE (eye protection and a respirator) and adequate ventilation are required. Follow the SDS for first‑aid procedures and handling precautions.
