Rust-Oleum 12oz Automotive High Heat Primer Spray Paint

It’s versatile and suitable for bare metal and a variety of surfaces including wood, metal, plastic, brick, concrete, and vinyl, making it useful for many DIY and automotive projects.

It’s engineered to withstand intermittent temperatures up to 2000°F (1093°C), which makes it suitable for components like engine blocks, mufflers, and exhaust systems where heat is a factor.

Yes—this product combines primer and topcoat in one, eliminating the need for a separate primer while still delivering durable adhesion and corrosion protection.

One 12 oz can covers about 10–12 square feet, depending on surface porosity and application method. Because this is a primer-paint-in-one, you’ll typically achieve the coverage with fewer coats than a separate paint and primer process, but apply as needed for even color and finish.

The product line offers a range of metallic colors to suit different project needs and aesthetics.

The any-angle spray system allows you to spray in awkward or tight spots (even upside down in some cases), and the comfort tip features a wider finger pad to reduce fatigue and help you apply a smooth, even coat.
