Today I'm saving an old 25 ACP pistol that was recently involved in a garage flooding, refinishing and repairing it. I'll take the opportunity to show you in detail how hot bluing works, and what is the best way to do it on a small scale.

A special thanks goes to Michelangelo Neri Orliani for helping in the making of this project
