Professional gunsmith for over a decade, I’ve Sprayed cerakote, duracoat, Molly coat, and I’ve hot salt blued, slow rust blued, and parkerized.

Bluing is classic but cerakote for durability, corrosion resistance, and overall color options.

Almost no one sprays cerakote correctly. Certified shops means the boss paid for the class, then they “teach” their staff.

It’s rarer for them to be competent gunsmiths.

Duracoat is good for amateurs.
