Rust-Oleum Automotive Flat Gray Oil-based High Heat Spray primer ( NET WT. 12.0-oz ) 6 -Pack
Can it be used to paint the inside of a fireplace? Switching to a metal bio-fuel insert and want to cover up old wood/gas stains?

We appreciate you reaching out. We are unable to recommend any of our products, including the Rust-Oleum High Heat Primer for applications that are in direct contact with the heat or flame. The product will flake or scorch if used in direct contact. If you were painting the outside of the fireplace, as an example, then you can use the product. We hope this helps clear up any confusion. - Rust-Oleum Product Support 1
