Zynolyte® Hi-Temp Paint is a lame resistant and heat resistant coating uniquely formulated to produce a lasting finish that is resistant to surface temperatures reaching up to 1,200°F (649°C). It is expressly designed for use on metal surfaces subject to extreme heat. Benefits: Best used where high temperature protection is vital. Use on interior and exterior applications. Fast drying. Once cured, this product is extremely tough, offering a hardened surface coating resistant to corrosion and pitting of the surface it covers. Will not chip off or peel away. Will not discolor or chalk. Offers excellent resistance to gasoline, rust, salt...

Enamel paint is paint that air-dries to a hard, usually glossy, finish, used for coating surfaces that are outdoors or otherwise subject to hard wear or variations in temperature; it should not be confused with decorated objects in "painted enamel", where vitreous enamel is applied with brushes and fired in a kiln. Typically the term "enamel paint" is used to describe oil-based covering products, usually with a significant amount of gloss in them, however recently many latex or water-based paints have adopted the term as well. The term today means "hard surfaced paint" and usually is in reference to paint brands of higher quality, floor coatings...

Application Tips Sand the engine thoroughly. You can use a wire brush to help remove old paint and debris. Clean the block with a grease and wax remover prior to painting to remove oils and other chemicals. Wipe down the engine to remove loose particles or use an air hose to clean debris. Start with a high-heat engine enamel primer for maximum corrosion resistance and uniformity of your top coat color. Apply primer and top coat engine enamel color with a light “tack” color first to avoid runs and sags. With spray applications, use a long, sweeping motion to apply the paint...

Enamel paints typically offer a hard, glossy finish and have excellent color retention. In addition, enamel can provide superior heat resistance—a must for automotive engine use. Because under hood temperatures generally run between 250 and 300 degrees, a good engine paint is usually rated to handle temperatures up to 500 degrees—and beyond.  When properly cured, enamel paints not only offer excellent chip resistance, they also resist rust and corrosion. They are also fairly simple to apply—either by brush, roller, or spray, depending on the paint—making them easy to work with even when your engine is still inside the engine bay. The most common engine paints are...
