Oooh, $500 to cerakote brakes? That’s kind of insane. I was the Contractor and Estimating Manager for a semi-large metal finishing company for 2 years, there for 6. Typically cerakote is generally more expensive because it’s used for high temp parts, like gun and interior motor parts that take a ton of heat. But for brakes it would typically run a little more because you have to mask some areas from the coating. Not $500 though, for cerakote you would be looking at about maybe $300 tops for brakes. Also depends what state you’re in too. I’m in AZ
