I explain what cold blue really does, why it will not make a gun factory new, and where it belongs. I share the Texas way I learned from my granddaddy's gunsmith shop, including the simple kit, proper preparation, safety precautions, testing, application, rinsing, and oiling. I also walk through the mistakes that cause blotches, rust, damaged finishes, and lost value on collectible guns. I’ll show you when cold blue is the right touch-up for a small spot, when it is the wrong choice, and why an old honest finish may be worth preserving instead of replacing.
