Cold bluing is a quick and easy way to put the color back onto steel parts. Let me show you this simple process.
These small parts are from a Winchester Model 67 and we've polished them to a 240-grit finish. We'll be using a cold bluing kit that has everything we'll need.
It's essential to remove all the oil and grease using a degreasing solution, and it also helps to warm the parts up a bit. Apply the cold blue solution generously, you'll start to see the results immediately.
Now rinse the parts in distilled water, dry them off, and then rub the surface lightly with degreased 4/0 steel wool. Repeat these steps to get a darker color.
When you're happy with the results, apply some oil and you're finished. Cold bluing small parts is a whole lot easier than polishing them.
