This gallon-size, black gloss coating delivers a nationally VOC-compliant finish engineered to resist heat degradation on components that see regular thermal cycling. It is part of a three-tier high heat coating line, occupying the General Purpose tier. Licensed coating applicators, HVAC technicians, and industrial maintenance professionals apply this product to protect heat-exposed metal substrates in residential and light commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis coating is intended for metal surfaces subject to moderate heat exposure, such as furnace housings, heat shields, exhaust components, and similar equipment where surface temperatures do not exceed 400 degrees F. Two coats are recommended for best results. The product is available in a gallon container, making it suitable for larger surface areas or multi-unit service jobs. It is offered alongside aluminum-finish variants across all three performance tiers in the RUST-OLEUM High Heat Coating line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for surface temperatures up to 400 degrees F (204 degrees C)\u003c\/li\u003e\n  \u003cli\u003eBlack gloss finish for a clean, consistent appearance on heat-exposed metal\u003c\/li\u003e\n  \u003cli\u003eNationally VOC-compliant formulation\u003c\/li\u003e\n  \u003cli\u003eGallon container suitable for larger or multi-surface applications\u003c\/li\u003e\n  \u003cli\u003eTwo-coat application recommended for maximum protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for metal surfaces exposed to intermittent or sustained heat up to 400 degrees F, including furnace housings, heat shields, and similar components in residential and light commercial HVAC and industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSurface preparation is critical before applying high heat coatings — remove rust, scale, grease, and loose material using wire brushing, sanding, or appropriate chemical prep. Apply in a well-ventilated area and allow full cure time before exposing the coated surface to heat. Two coats are specified by the manufacturer for best performance.
