Rust Oleum CombiPrimer Anti Rust Metal Primer Spray Paint

The Rust-Oleum CombiPrimer Anti Rust Metal Primer in Grey, 400ml is a high-performance anti-corrosion primer based on an aromatic-free short oil alkyd resin. This Grey variant is a popular choice for general industrial applications where a neutral, professional base coat is required before applying a topcoat.

Formulated with rust-inhibitive pigments and free from lead and chromates, it is suitable for use on new or rusted steel surfaces. Unlike the aerosol variant, this product is primarily intended for brush application, though roller and air spray are also suitable — making it versatile for a range of project scales.

Best suited to general industrial exposures, normal humidity, and interior applications, it should be recoated with CombiColor Metal 7300.
