Hi-Tech Engine Paints GM Blue

Hi-Tech Engine Paints GM Blue is a professional-grade engine enamel designed for restoring and refinishing factory-correct engine blocks on General Motors vehicles. Whether you're rebuilding a classic Chevy small-block, refreshing a modern LS platform, or detailing a show-quality engine bay, this aerosol paint delivers authentic GM Blue color matching that engine enthusiasts and restoration shops trust. Engine bay aesthetics matter—original color accuracy separates a proper restoration from a half-measure, and this high-temperature formulation ensures your finish survives the thermal cycle of modern powerplants.

Formulated as a high-temperature alkyd enamel, Hi-Tech Engine Paints GM Blue withstands continuous exposure to engine heat, oil vapor, and thermal cycling without chipping, fading, or peeling. Alkyd enamel chemistry provides superior adhesion to cast iron and aluminum block surfaces while curing to a durable, semi-gloss finish that resists solvents and detergents used in engine cleaning. The 16 oz aerosol delivery system enables precision application in tight engine bay spaces—valve covers, block flanks, and accessory mounts—where brush or roller application becomes impractical. Heat resistance up to approximately 400°F ensures the finish survives normal engine operating temperatures without degradation.

This product suits engine rebuilders, restoration specialists, and DIY enthusiasts tackling engine bay cosmetics on Chevy and GM platforms spanning decades of production. Before application, thoroughly degrease the block with solvent, lightly sand with 150–220 grit to establish tooth, and apply thin, even coats from 6–8 inches distance. Multiple thin passes outperform single heavy coats—expect 2–3 applications for full coverage and optimal color saturation. Allow proper cure time between coats and before engine startup to achieve maximum adhesion and heat resistance.
