Eastwood High Temperature Internal Exhaust Coating
Eastwood’s High Temperature Internal Exhaust Coating is designed to coat the inside of exhaust system components, helping to keep heat inside the tubing and reduce under-hood temperatures. The coating is formulated to withstand extreme heat, with a thermal resistance up to 1800 degrees Fahrenheit. This product is intended for exhaust components where heat management is critical, such as headers and manifolds. Application involves preparing the area, applying the coating, and allowing it to cure, after which it contributes to heat retention and potential performance benefits by reducing thermal stress on surrounding parts.
Design Engineering High-Temperature Aluminum Silicone Coating Spray
Design Engineering’s High-Temp Silicone Coating Spray offers protective sealing for exhaust wraps and metal surfaces exposed to high heat. With the ability to withstand temperatures up to 1200°F, this coating penetrates, seals, and guards against dirt, debris, and grime. It is suitable for shielding headers, exhaust manifolds, and other hot components, helping to preserve heat retention where wraps or heat shields are used. The coating is designed for durability and ease of reapplication as needed to maintain performance in demanding environments.
CERAKOTE Glacier Black [4oz] C-7600T
CERAKOTE Glacier Black offers a rustic satin finish with ceramic technology designed for robust chemical and UV resistance. The Glacier Black color provides a stealthy, matte look that can be applied to a variety of metals and substrates, including hot exhaust components. This product is noted for delivering a resilient ceramic layer that helps protect against environmental exposure, chemical attack, and oxidation while maintaining a durable finish through repeated heat cycles. It is compatible with multiple application methods and surfaces without requiring a catalyst for curing.
CERAKOTE Platinum Rapid Ceramic Paint Sealant Spray
CERAKOTE Platinum Rapid Ceramic Paint Sealant Spray is designed to deliver a high-gloss, hydrophobic ceramic coating with quick application. It provides a durable protective layer that enhances sheen and slickness while offering resistance to washing and environmental contaminants. Although marketed for vehicles, its ceramic formula can be advantageous on hot engine components and exhaust-related surfaces that demand a tough, long-lasting finish. The product emphasizes ease of use—apply a light coat and buff to a showroom-like shine.
Dupli-Color Cast Coat Aluminum Engine Enamel with Ceramic
Dupli-Color Cast Coat Aluminum Engine Enamel with Ceramic combines enamel chemistry with ceramic resins to resist heat up to 500 degrees Fahrenheit. This combination delivers a protective layer designed for engine components, including headers, where heat exposure is significant. The product features an EZ Touch conical nozzle for straightforward application and aims to maintain high gloss retention while providing durable protective properties against heat and chemical exposure. It is suited for enthusiasts seeking a vibrant yet resilient finish on aluminum engine parts.
Buying Guide
- Heat rating: Match the coating’s temperature range to the component’s exposure. Exhaust headers can see extreme temps, so coatings rated for higher temperatures are preferable.
- Surface compatibility: Confirm whether the coating adheres to metal, aluminum, or wrapped surfaces. Some products are designed specifically for wraps, others for bare metal.
- Finish and appearance: If aesthetics matter, choose a finish (matte, satin, gloss) that aligns with your goal. CERAKOTE Glacier Black and Platinum offer different looks and protection levels.
- Durability and chemical resistance: Consider UV, chemical, and abrasion resistance for long-term durability in under-hood conditions.
- Application process: Some coatings require multiple coats, curing times, or prep work. Follow manufacturer instructions to achieve the best seal and longevity.
- Reapplication: High-heat environments may require periodic reapplication. Plan for maintenance cycles to maintain performance.
- Brand ecosystem: Reputable brands like CERAKOTE, Eastwood, and Design Engineering have established support and compatible products for future projects.
- Intended use: Some products are optimized for exhaust interiors, wraps, or exposed surfaces. Align the product with your specific header or manifold configuration.
