BILL HIRSCH ENGINE ENAMEL: TECHNICAL DATA & FAQ
The Gold Standard for Antique and Collector Car Restoration
PRODUCT OVERVIEW
Bill Hirsch Engine Enamels are high-gloss, high-solids coatings engineered with the same high-quality components used in jet aircraft engine enamels. For over 40 years, these enamels have been the preferred choice for professional restorers and show-car owners worldwide.
Aerospace Pedigree:
Manufactured by specialists connected to the aerospace industry. The only difference between our engine enamel and jet engine enamel is the color. Unrivaled Longevity: Our formula has been proven over four decades. Engines painted 40 years ago still retain their finish today. Authenticity: We offer over 60 period-correct colors for Buick, Cadillac, Chevrolet, Chrysler, Ford, Packard, Pontiac, and more.
PERFORMANCE SPECIFICATIONS
Extreme Heat Resistance: Rated to withstand up to 700 Deg F. Thermal Shock Stability: Can handle rapid temperature shifts from -50 Deg to 700 Deg F without affecting the finish. Chemical Resistance: Fully resistant to gasoline and oil once the finish has fully hardened and cured (approximately 2 weeks).
SURFACE PREPARATION
Cleanliness: Surfaces must be 100% free of oil, grease, or foreign matter. Mechanical Prep: Remove loose scale and wire brush the surface. Sandblasting is not required for cast iron blocks but can be used if desired. Priming: No primer is needed on cast iron or cast aluminum blocks and cylinder heads. However, a high-temp primer is recommended for steel valve covers or smooth aluminum parts to ensure the best adhesion.
APPLICATION METHODS
Brushing: Use directly from the can. The formula is designed not to splatter, making it ideal for engines that are still in the vehicle. Spraying: Apply a very light "mist" coat first. Wait 2 minutes until tacky, then apply a heavy final coat. Thinning: If thinning is required for spray equipment, use approximately 1 ounce of Xylene (Xylol) or a high-quality slow-drying lacquer thinner per quart.
CRITICAL INSTRUCTIONS & WARNINGS
Curing Time: Do not start the engine for at least 10 days. Starting the engine before the paint has fully cured can cause "wrinkling" or "crinkling."
Environmental Conditions: Do not apply paint if the temperature is below 60 Deg F or above 80 Deg F, or if the humidity exceeds 80%.
Exhaust Manifolds: Do NOT use engine enamel on exhaust manifolds, as they frequently exceed 700 Deg F. Please use specialized Bill Hirsch Exhaust and Manifold Finishes for those areas.
Aerosol Caution: Never use an aerosol can to touch up a surface that was originally brushed for at least 4 months. The stronger solvents in the aerosol formula can attack and damage the brushed finish.
