I talked to Joel Kendrick, the best guy to do it, and he told me he could turn a barrel around in a week. It is highly recommended that you shoot the barrel enough to break it in before the process. Any burrs or rough spots will mess up the process. Even in a well lapped barrel, break in is required.
Does anyone know what Remington used to coat there stainless 7 mag barrels back in the sixties? It must have been some sort of bluing but it didn't stick very well. The barrel would usually look like an apaloosa after a few years. I bead blasted one with 220 grit and it looked pretty good
