What Is Cerakote?
Cerakote is a polymer-ceramic composite coating applied in thin layers and cured at high temperature. Unlike traditional bluing or anodizing, Cerakote bonds at the molecular level to create a barrier that resists corrosion, chemicals, and abrasion far beyond what bare metal or standard finishes can achieve. It is available in hundreds of colors and can be applied to virtually any firearm surface.
The Test Protocol
We took two identical receivers: one hard-coat anodized (mil-spec Type III) and one Cerakoted in Armor Black (H-190). Both were subjected to 500 rounds of rapid fire, salt fog exposure for 72 hours, and repeated holster draw cycles. We documented surface condition at each interval with macro photography and measured coating thickness with a digital gauge.
Results and Takeaways
After 500 rounds, the anodized receiver showed visible wear at the charging handle contact point and along the upper rail. The Cerakoted receiver retained its finish with only minor burnishing at the highest-friction points. Salt fog testing widened the gap further: the anodized surface developed pitting at exposed edges while the Cerakote showed zero corrosion penetration.
For shooters who want the longest-lasting protection on a working firearm, Cerakote outperforms traditional anodizing in every metric we tested. The added benefit of color selection and the ability to coat any substrate, including polymer and stainless, makes it the clear choice for custom builds.
