Design Engineering High-Temp Silicone Coating Spray
Design Engineering’s High-Temp Silicone Coating provides an extra layer of protection for exhaust wraps, headers, and metal components. It resists dirt and grime, helping preserve performance. The coating is designed to withstand temperatures up to 1200°F, making it suitable for hot surfaces where heat retention and protection are crucial. In addition to protecting exhaust wraps, it shields adjacent metal surfaces, supporting longer component life in demanding environments.
Eastwood High Temperature Internal Exhaust Coating
Eastwood’s internal exhaust coating is formulated to coat the inside of exhaust system components, helping keep heat within the tubing. This reduces under-hood temperatures and extends the life of exhaust components. The thermal coating is rated to withstand up to 1800°F, enabling protection in extreme heat conditions often encountered in performance and diesel applications.
CERAKOTE Glacier Black Coating Kit (C-7600 16 oz.)
The Cerakote Glacier Black Kit includes everything needed to spray Cerakote with air cure. It delivers a durable, high-temperature ceramic coating rated to 1800°F, making it suitable for exhaust components and other high-heat surfaces. The kit provides a complete solution for users seeking professional-grade durability and protection without complex prep or curing steps.
CERAKOTE (AIR Cure C-Series Glacier Black 16oz)
CERAKOTE Glacier Black in the C-Series is a ready-to-spray air-cure ceramic coating designed for a deep, durable satin black finish. It maintains color and performance in extreme environments, making it a versatile option for exhaust components, manifolds, and other heat-exposed surfaces. The process does not require catalysts, simplifying the application for many users.
CERAKOTE Platinum Rapid Ceramic Paint Sealant Spray
CERAKOTE Platinum Rapid Ceramic Paint Sealant Spray provides a balance of gloss and protection with a high wash rating. While primarily marketed for paint protection, its ceramic chemistry and hydrophobic surface make it a candidate for lighter exterior hot-spot protection and assistance in maintaining coating integrity under heat exposure. Application is straightforward with a wipe-on, buff-to-shine approach.
CERAKOTE (AIR Cure C-Series Flat Dark Earth)
CERAKOTE Flat Dark Earth offers a flat, matte finish suitable for stealth applications or where a non-gloss surface is preferred. As part of the air-cure C-Series, this coating provides durable ceramic protection for metals and polymers with good heat resistance and environmental durability, making it applicable to exhaust components in many automotive contexts.
CERAKOTE C-Series Titanium Kit
The Cerakote Titanium kit provides an all-in-one solution for projects requiring a robust ceramic finish. The kit emphasizes air cure, no primer, and rapid tack-free times. It’s designed for durable protection against UV exposure and chemical stress, extending the life of exhaust parts and other high-heat areas under demanding operating conditions.
Buying Guide
When selecting an exhaust ceramic coating, consider the following factors to ensure the right fit for your project.
- Temperature rating: Choose coatings with a rated heat tolerance matching or exceeding your exhaust system’s operating temps. For hot exhausts, coatings rated to 1800°F offer additional headroom.
- Application method: Some coatings require oven curing or catalysts, while others are air-cure. Determine which process aligns with your workspace and comfort level.
- Application area: Decide between internal coatings (coating the inside of pipes) and external coatings (wrap protection or external surfaces). Internal coatings help retain heat and reduce under-hood temps, while external coatings focus on appearance and corrosion resistance.
- Finish and appearance: Glossy, satin, or flat finishes affect aesthetics and how forgiving a coating is to surface imperfections. Matte finishes may better hide flaws on engine bays.
- Chemical and UV resistance: High resistance helps maintain coatings’ integrity in harsh exposure environments, including fuels, cleaners, and sunlight.
- Ease of maintenance: Some coatings offer longer wash intervals or easier buffing, which matters for daily drivers and show cars alike.
- Kit contents and support: Fully loaded kits reduce additional purchases and simplify the process. Consider kits that include brushes, sprayers, or primers if needed.
- Surface preparation: Substrate cleanliness and proper scuffing typically enhance adhesion. Follow manufacturer guidelines for best results.
Across these options, users should prioritize heat tolerance, ease of application, and durability. For critical high-heat exhaust components, internal coatings and air-cure ceramic systems often deliver the strongest long-term protection. For wraps and external surfaces, high-temp silicone coatings and durable outer coatings provide effective protection against dirt, moisture, and temperature-driven degradation.
