Rust-oleum 286503 High Heat Coating 1 Gal Black Gloss

Product Description

The RUST-OLEUM 286503 is a General Purpose High Heat Coating formulated for metal surfaces exposed to sustained temperatures up to 400 degrees F (204 degrees C). 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.

This 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.

Key Features

• Rated for surface temperatures up to 400 degrees F (204 degrees C)
• Black gloss finish for a clean, consistent appearance on heat-exposed metal

Compatibility

Designed 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.

Installation Notes

Surface 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. Follow all applicable local VOC regulations and safety requirements for coating application in enclosed spaces.
