Too cold and windy for shooting so I thought I'd take a crack at fixing up the blueing on the Pre-B CZ75 I picked up last Fall. It was in good shape except for a fair bit of surface wear to the matte blued finish. I had picked up a bottle of Birchwood Casey blueing a few weeks ago and decided today was the day. I was surprised how easy it was and how good it turned out—it only took about 30 minutes!

Here are the before and after (as an aside, how do you get an idiot scratch on a CZ75? :confused:)

Looks good. Any chance of a short write-up of the procedure?

Sure! I didn't follow all of the instructions on the bottle (it was Birchwood Casey Perma Blue)—I was not crazy about the idea rinsing the frame or slide in cold water nor did I want to rub them down with steel wool. I field stripped the pistol, removed the grips from the frame, gave the slide and frame a good wipe-down with a rag soaked in rubbing alcohol and let it dry. I then used a few makeup pads (helps to be the only guy in the house) to apply the blueing. After I finished the application I let the parts sit for a minute or so, then wiped them down with a clean, dry rag and did it again a couple more times then rubbed BreakFree on the parts, let them sit for maybe 15 minutes or so, then rubbed that off. The CZ's steel seemed especially receptive to the blueing—after just the first pass I could see a difference.
 
These are great pistols. I have a collection of them. You couldn't beat the price that Allen Lever sold
them for back in the day. He obtained some very interesting models with various finishes from the
factory with low numbers. The 85 series is also a nice pistol

My first centrefire semi-auto was one of the "tropical" finish enamel models that I bought in 1986. I shot it for a few years then sold it for a S&W 5906. I'd forgotten how pleasant these pistol are to shoot—and how good the Pre-B SA trigger pull is. Here's the pistol last Fall from when I first got it.

Yes looks fantastic. Doesn't look like a typical refinish job at all, looks original.

Thanks for the write-up.
 
Looks like you did a fine job! I also like the before pictures too! So it's a win win to me....I was thinking of having my Beretta 92s refinished but I'd hate to lose the "historical" character so I think I'll get a second one, one to keep original and one to get custom finishing.
 
That turned out very nicely Master-G. The only negative thing I found with cold bluing is that it doesn't penetrate to well to sharper edges and tends to wear quickly in those spots.

I want to try OX-PHO BLUE sometime as well http://www.rustywood.ca/shop_home/ox-pho-blue-4oz/


I did do my entire S&W revolver with Birchwood Casey Super Blue. I tracked down some 0000 steel wool at Home Hardware made by Bulldog, it works great. Birchwood Casey has some helpful tips and refinishing with there products https://www.birchwoodcasey.com/Manage/literature/refinishing-guide-2013.aspx



PS, if you have a cut near your fingers, wear gloves because it burns like a MOFO. They advised to wear gloves anyway but... ummm I didn't lol. Not to hijack your thread Master-G, this pic below is my finished revolver

I took the plunge and did my P7's slide last night—similar to the CZ75 the pistol was in good mechanical shape, even better actually, but showed a lot of what I'm guessing was holster wear as it was a German police surplus pistol. I could probably do a bit more on the slide's left side but other than that I'm very pleased with the way it turned out!
