Rustoleum Heat Paint Buyer’s Guide

Rustoleum High Heat Paint

So we have reviewed three of Rustoleum high heat paint. Any of them reviewed here is worth it. However, you may end up picking the wrong one for the job.

The following 2 criteria will help decide which you should use for your project.

Maximum temperature of the item

If you use a standard paint to apply on highly heated surfaces, even though it may bond, when the temperature of the item is increased, the paint peels off or forms bubbles. Hence, the need for high heat paints.

If you intend to use high heat paint for your project, you must use a paint that can withstand the possible highest temperature.

Automobile engines have the highest temperature from over 500°F. So it makes sense to go for either of the Rustoleum heat paints with heat resistance from 1000F. For painting other lower heated items like grill and stoves, the 500° F will be great.

Method of application

Rustoleum heat paints are available in a spray can and oil paint. Spraying is always more efficient as it gives you a smoother finish.

If you do not want the stress and hassles associated with brushes, you will want to go for the spray can. The advantage of spraying is that you can spray into hard to reach areas effortlessly than brushes. For a bigger project, you can buy the larger 1-quart quantity and use an HVLP sprayer for application.
