“You can have a car in any color, as long as it is black” said Henry Ford once. Blue or stainless used to the choices for guns, but not anymore. Several options are now available, with Cercoat being popular for its exceptional resistance to wear. Unlike dyes added to plastic, Cercoat makes the gun tougher and the grips easier to retain on recoil. With the same color or pattern possible on metal and plastic, it is also quite good for providing consistent finish for whole firearm.
Spectrum Coating does Ceracoating for Kel-tec weapons. Steven Taylor, the owner, is an artist at heart and also restores old, beat-up guns just to show what can be made of a rusted-out flea market buy with care and expertise. I still remember when synthetic stocks became common: the Internet discussions derided the non-traditional look. Considering that prior to the early 19th century guns were far more individualized that after the onset of mass production techniques, custom firearms represent a return to tradition, albeit with a technological update.
