Let's talk about this! If a paint is applied too heavily, it can start to crack and look almost like mud as it starts to dry. While some paints cure over time, Rust-Oleum Specialty High Heat Ultra Spray Paint needs to be heated to fully cure. Because of this, we recommend this product for use on the exterior of barbecue grills, wood stoves, radiators, fire pits, fireplace screens, and automotive parts. We recommend raising the temperature of the surface to 450°F for an hour to fully cure it. If the surface does not reach temperatures above 200°F, then one of our standard spray paints may be a better option. If needing further assistance, please give us a call at 800-481-4785 to talk with us.
