Rust-Oleum® Specialty High Heat Paint is a premium performance paint specially formulated to renew and protect metal surfaces exposed to extreme heat up to 648 °C. Designed for both DIY and professional applications, this brush-on coating delivers durable rust resistance and colour retention where other paints fail.
Unlike standard coatings, the High Heat formula stands up to repeated thermal cycling – making it ideal for outdoor and indoor heat-exposed metal surfaces. Perfect for updating grills, wood-burning stoves, fire pits, automotive components, radiators and more.
Whether you’re refurbishing your BBQ, restoring a vintage motorbike part, or protecting structural metalwork from heat and rust, this paint provides a long-lasting, high-heat finish you can count on.
