This wiki has been updated 14 times since it was first published in April of 2018. Extreme temperatures encourage oxidation, which leads to rusting, pitting and, ultimately, a loss of structural integrity. The right coating goes a long way toward preventing this, and these high-temperature paints have insulating properties that can protect exhausts, engine manifolds, industrial machinery, outdoor grills, smokers, wood-burning stoves, chimney caps, and more.

Editor's Notes

November 11, 2020:

In this update, we added the Rust-Oleum 251591 to the list, which is a reliable, protective coating for a vehicle’s brake calipers, drums, rotors, and springs. It’s available in black or red, and you can adjust the spray angle, as needed. It resists dust and rust, and can handle temperatures up to 900 degrees Fahrenheit. It’s made in the United States by a leading name in rust protection and joins the quick-drying, satiny Rust-Oleum Enamel and the long-lasting matte Rust-Oleum Automotive on the list. We’re still partial to the POR-15 44000 Series, which stands up to harsh weather and salt, making it a good choice for outdoor grills. It’s also commonly used on fireplaces as well as engine manifolds. You can choose from among black, gray, or aluminum colors, and sizes that include 8 ounces, 1 quart, and 1 gallon. To make room from the new addition, we say goodbye for the Corr-Paint 3015, which is relatively pricey for its small quantity of just 1 pint.

If you’re into restoring hot rods, chances are you’re no stranger to KBS Xtreme, which is specially formulated to protect metal surfaces and can withstand temperatures of up to 1,500 degrees Fahrenheit. It’s available in eye-catching colors like Rocket Red, Flame Blue, Jet Black, Pure White, and more. As you might have guessed from its name, Stove Bright is designed for coating wood burners. It features attractive metal flakes and will hold up for the long haul. As stated in our last update, for safety’s sake, be sure to apply these paints in a well-ventilated area such as an open garage. Safety glasses or a face mask will protect your eyes and minimize the inhalation of fumes.

High temperature paints are a simple, budget-friendly way to rejuvenate items that are often subjected to high temperatures, including engine systems, machinery, outdoor grills, chimney caps, and more. Here we provide you with a range of options that will help to prevent rusting, pitting, and other forms of damage.

Coming on board in this update is Rust-Oleum Enamel High Heat, which comes from one of the best-known brands in protective coverings. This versatile selection works well on grills, wood-burning stoves, and other metal items and comes in a variety of sizes, including quarts, pints, gallons, and a convenient 12-ounce spray bottle. It features a rich, satin finish and can withstand temperatures of up to 1200 degrees Fahrenheit. It dries quickly and can be used either indoors or out.

Remaining in the top spot is the POR-15 44000 Series, which can be used on manifolds, headers, exhausts, and stacks and resists cracking, chipping, and peeling like a champ. It’s resistant to salt and moisture, as well as mild industrial films.

Leaving the list today is the Cerakote C-Series, due to issues with availability.

For safety's sake, always paint in an open, well-ventilated area, and follow all safety guidelines carefully that are included with your product.
