Eastwood High Temperature Internal Exhaust Coating
Eastwood’s internal exhaust coating is designed to line the inside of exhaust components, keeping heat inside the tubing and lowering under-hood temperatures. The coating withstands up to 1800 degrees Fahrenheit, delivering thermal protection for pipes, manifolds, and headers. The product helps reduce thermal fatigue and provides a durable finish that resists cracking and peeling under heat cycling. Application typically involves cleaning the surface, applying a coated layer, and allowing proper curing according to instructions.
Design Engineering High-Temperature Aluminum Silicone Coating Spray
This high-temp silicone coating from Design Engineering provides robust protection for exhaust wraps and metal surfaces. It is formulated to handle temperatures up to 1200°F, sealing and protecting the wrap while improving heat retention. The coating helps shield metal surfaces from dirt and grime, extending the life of heat-exposed components. Its penetrating, sealant properties make it a practical choice for high-heat applications in and around the exhaust system.
CERAKOTE Glacier Black Coating Kit (C-7600 16 oz.)
The Glacier Black Coating Kit provides an all-in-one solution to spray CERAKOTE on metal substrates. It offers an industry-leading 1,800°F temperature rating, making it suitable for demanding exhaust and engine components. The air-cure system eliminates the need for ovens or catalysts and becomes tack-free quickly, enabling a straightforward, field-friendly coating process with durable, heat-resistant results.
CERAKOTE (Air Cure C-Series Glacier Black 16 oz) C-7600P
The Glacier Black C-Series from CERAKOTE delivers a durable, color-stable ceramic coating designed for high-temperature environments. This air-cure option provides a corrosion and UV-resistant finish suitable for exhaust components while maintaining a sleek, dark appearance. It is ideal for parts that require a robust ceramic layer without the complexity of post-curing or catalyst use.
CERAKOTE C-Series Titanium 4 oz Project Kit
The CERAKOTE Titanium project kit equips users to spray a high-performance ceramic finish with air-curing capability. The kit includes components needed to apply the coating to metal surfaces, delivering excellent UV stability, chemical resistance, and a durable ceramic layer that protects exhaust-related parts from heat and environmental exposure. It pairs well with other CERAKOTE products for layered protection and color consistency.
Buying Guide: Key Considerations For Exhaust Ceramic Coatings
- Temperature rating: Choose coatings rated for the highest temperatures your exhaust components will encounter. For severe heat, products rated to 1800°F offer greater margin.
- Surface preparation: Most coatings require cleaning and sometimes light surface prep. Follow manufacturer guidance to achieve optimal adhesion and longevity.
- Application method: Some coatings are spray-on and air-cure, while others may require curing ovens or heat activation. Consider your workshop capabilities and whether an air-cure option suits you.
- Interior vs exterior coating: Internal exhaust coatings seal heat inside the tubing, while external coatings provide corrosion and UV resistance and a finished look. Select based on whether you coat inside surfaces or outer shells.
- Color and finish: If aesthetics matter, Glacier Black and other color options provide a consistent appearance. Note that some coatings maintain color under heat cycling while others may change over time.
- Durability and maintenance: High-durability ceramic coatings resist chemical exposure, road grime, and moisture. Quick-touch-up options can help maintain performance between full re-coats.
- Warranty and compatibility: Review product warranties and compatibility with existing exhaust wraps or components to ensure seamless integration.
- Layering and recoat intervals: Some systems allow multiple coats for thicker protection. Check recoat windows and cure times to minimize downtime.
