Why pick Patriot's Metallic Ceramic Coating finish?

Our Metallic Ceramic Coating protects and extends the life of headers by creating a thermal barrier which significantly lowers under hood temperatures and protects the substrate metal from thermal fatigue. After the Metallic Ceramic Coating is applied, it is polished with a vibratory finishing process that produces a high luster aluminum appearance. The polishing process compresses and activates the coating, creating a surface which is harder and 60% more corrosion resistant than an unpolished surface.
