Seymour MRO Industrial Strength Primer Light Gray

Seymour 620-1431 is a high-solids, VOC-compliant industrial primer in light gray, designed for MRO (Maintenance, Repair & Operations) use. It offers up to 3–4 times the coverage of standard aerosol primers, resists runs and sagging, and forms a rust-proof, durable base layer that bonds tightly to metal surfaces. This primer protects against corrosion, weather, oil, gasoline, and most corrosive chemicals while resisting abrasion and heat (up to 300 °F), making it ideal for equipment, structural steel, and machinery preparation.
