Questions & Answers
Can this primer be used on an aluminum wall exhaust from a propane stove? It's outside on the wall about 6 feet from stove.
Thank you for reaching out, Steve. While Rust-Oleum Automotive High Heat Primer can withstand temperatures up to 2000°F, we only recommend using it for automotive applications. Instead, we recommend applying our Rust-Oleum Specialty High Heat Spray Paint, as it can withstand temperatures up to 500°F without the need to heat cure the paint. https://www.homedepot.com/p/Rust-Oleum-Specialty-12-oz-High-Heat-Ultra-Semi-Gloss-Black-Spray-Paint-6-Pack-241169/203161207 -Rust-Oleum Product Support 14
will this high heat primer adhere to magnesium ? this is for valve covers for a car
Happy to help! Rust-Oleum Automotive High Heat Primer Spray can be used on metal surfaces, as long as they are not galvanized. Make sure to clean and sand as directed to ensure full adhesion. - Rust-Oleum Product Support 3
Does the primer need to be heat cured before applying topcoat? Also, how can I heat cure the item if it is too big to fit in the oven?
Let's talk about this, Andy. The Rust-Oleum Automotive High Heat Gray Primer Spray needs to be heat cured in order for it to work properly. For items off a vehicle, we recommend that it's baked at 250° F for 30 min, and then allowed to cool for 30 min. Then, bake at 400° F for 30 min, and allowed to cool for 30 min. You'll then move to bake the item at 600° F for 30 min and then allow 30 min to cool for curing. If your surface doesn't exceed 200 °F, we may be able to help find a different coating for you.

Can this be applied to radiator at home?
Thanks for reaching out. Rust-Oleum Automotive High Heat Primer Spray is for use on automotive engines and other automotive surfaces that reach intermittent temperatures up to 2000°F. High Heat Primer requires heat curing, raising the temperature to 600°F to dry properly, it cannot be used on radiators. Any Rust-Oleum Paint can be applied to metal surfaces that do not exceed 200°F. - Rust-Oleum Product Support 6
Can I use high heat paint or primer on furnace and water heater? If I can do I need to use high heat primer 1st then acrylic latex or high heat?
Happy to clear things up, Patti. Rust-Oleum Automotive High Heat Primer Spray does require a heat cycle to fully cure the primer, and it does need to be able to reach temperatures up to 600°F for 30 minutes in the last cycle. This primer would then need to be topcoated with a high heat paint. Please keep in mind, if the surface does not reach temperatures above 200°F, then most of our spray products can be used without issues of the heat affecting the coating. - Rust-Oleum Product Support 3

Can this paint be used as primer for an aluminum barbeque grill?
Thanks for reaching out. Rust-Oleum Automotive High Heat Primer is designed for use on automotive engines and other automotive surfaces which reach intermittent temperatures up to 2000°F. This primer is not recommended for barbeque grills since it must be heat cured at varying temperatures up to 600°F for 30 minutes. - Rust-Oleum Product Support 6
I would like to paint my ductwork a metallic copper finish but it’s recommended to use a high hear primer first. Hopefully your product will work.
We appreciate your interest, Frankie! Rust-Oleum Automotive High Heat Primer Spray is intended for use on metal surfaces that reach temperatures well above 200°F. To ensure a full cure, you will need to heat the surface as directed for items off the vehicle. - Rust-Oleum Product Support 3
