Primer Header Paint Flame Proof

VHT Primer Header Paint Flame Proof is a specialized high-temperature aerosol coating engineered for engine headers, exhaust manifolds, and other underhood components exposed to extreme heat cycling. Whether you're building a performance engine, restoring a classic vehicle, or protecting aftermarket exhaust systems, this flameproof primer provides the durable foundation that professional mechanics and automotive enthusiasts demand when aesthetics and longevity matter equally.

This 11 oz aerosol delivers a silicone ceramic formulation rated for sustained high-temperature applications, forming a flat white primer base that resists thermal stress, oxidation, and flame exposure far beyond conventional automotive primers. The silicone ceramic matrix bonds at the molecular level to bare steel and cast iron, creating a protective barrier that prevents rust formation and extends component life under hood temperatures that routinely exceed 500°F. The flameproof characteristic ensures the coating itself remains stable when exposed to open flame or radiant heat from headers and turbo manifolds, making it ideal for competition engines, turbo builds, and heavily modified drivetrains.

Mechanics and engine builders use VHT primer as the first step before applying high-temperature topcoats, creating a multi-coat protection system that outlasts single-stage finishes by years. The flat white finish provides excellent contrast for inspecting coverage and serves as an ideal base for VHT's full line of ceramic header paints available in multiple colors. Application is straightforward—shake well, spray in light, even coats, and allow proper flash-off time between layers. Compatible with all ferrous metal engine components, this primer works equally well on street vehicles seeking factory-grade protection and race engines where thermal management directly impacts component reliability.
