Mueller Coatings

Mueller Coatings has been a family-owned operation since its founding, now in its third generation under Glenn Mueller's leadership. What started as a general coating shop has evolved into a specialized provider serving aerospace, defense, medical, and firearms industries.

Their primary offering for the firearms community is Cerakote application—a ceramic-based coating system that's become the gold standard for firearm protection and aesthetics. Mueller is Cerakote certified and equipped with professional-grade equipment:

• •Manual spray cells for precision hand work
• •Automatic spray cells for consistency
• •Six-axis robotic spray cell for complex geometries

Cerakote delivers what shooters actually care about:

• •Corrosion resistance that outlasts traditional bluing and Teflon
• •Heat resistance for barrels and high-wear components
• •Chemical inertness against cleaning solvents and ammunition residue
• •Custom colors—the full Cerakote palette available
• •Reduced friction on internal components

"Cerakote is renowned for its exceptional durability, heat resistance, and chemical inertness."

Mueller operates under strict certifications:

• •ISO 9001:2015
• •ISO 13485 (medical device standards)
• •AS 9100 (aerospace standards)
• •ITAR compliance

They've completed FAA testing including flammability, combustion toxicity, and biocompatibility—standards that exceed what most firearm coating shops maintain.

While Cerakote for firearms is their specialty for shooters, Mueller also serves aerospace, defense contractors, medical device manufacturers, and automotive industries with the same precision and equipment.
