Cold blued and scratched....

[Gottmituns]

Last night I cold blued the slide on my CZ-82. The original paint was badly chipped.
I prepped it very well, cold blued it, put oil on it, left it overnight so it could cure. I finished the whole thing at 1:00am. This morning I was marveled at how nice of a job it turned out to be. All was hunky dory till I scratched it by using a punch out to insert the pin that holds the extractor. You know, I started with the rubber hammer, it went in, but did not seat all the way. I needed to insert the pin about 1 mm underneath slide level. The punch out slipped when I hit it with the hammer and left a 1/2" scratch on the slide between the pin and the extractor. Any suggestions? I was bummed out, I reassembled it to the frame, tucked the CZ82 back into the svb500 and came to the office....

Sorry to hear that.  Sounds exactly like something I would do.

The seemingly easy things are the most delicate.
A buddy suggested I use a Birchwood Casey blue pen. I'll try that.

The Birchwood Casey products I have used were for alloy frames.  Not sure how they will do on steel.  I really feel for you as I know how frustrated you must be.

Sorry about the scratch! I hope you will post a picture of your cold blue job.  I have an 83 that I would like to do myself if possible.  What brand cold blue did you use?  My 83 is not painted and was originally blued although the bluing is more like a very dark gray/graphite color.  Is cold bluing as durable as hot bluing?  I saw a DIY bluing video where a guy soaked the parts in a rust remover to remove the old bluing.  Parts came out of that solution looking brand new.

I'll post the pics as soon as I find out what I'm going to do with it once I get home.  I am fearful of opening up the speedvault and finding rust over the scratch.

You know, last night I blued it twice because I overlooked two spots on the slide (the rails) and did not apply oil to them. 5 minutes into the curing process, I turned the slide over for one last looksy, and sure enough, major rusting in those spots. As if the gun had gone to war..

I degreased, removed the blueing, and started over. That second time, after applying the cold blue/water/dried rinse and repeat to where I wanted it, I oiled every nook and cranny of the CZ82. The living room smelled terrible. I had the fan on, with air circulation. But still that rust & blue remover liquid stank something fierce. I got hell from my wife.

I'm worried, well, wondering if the slide scratch has developed rust already on it...


(I also polished the extractor so It would contrast nicely with the blued slide. Darn scratch above the extractor. If the scratch were on the other side of the slide, I would not be so concerned. But it's on the business side...)

Oh, yeah, I used Birchwood Casey Blue kit. It is amazing. True to what they advertise. Once the slide is prepped (that the main part), the blue application does what it says it does. A beautiful dark/black tint to the slide.

Darn scratch....

I know the scratch sucks,  but thank you for the information.  I will give this a try in my garage! I have a wife too!

Good luck. I know your CZ-83 will turn out excellent.

Here is a solution to your scratch from Birchwood.

Just what I was fixin' to suggest!

Thanks guys. i did order the pen from Amazon. My LGS did not have it.
So, what I ended up doing.... Went to home depot, bought some 120 and 600 grit, shop towels, steel wool and more latex gloves (cheapo gloves, I had to change em every 5 minutes).
And I took it upon my self to re-blue the slide...
Right now, I am super tired, haven't slept very well, the slide is soaking in CLP for the curing process. I did spray it with rem-lube at first but it dried up instantly (or at least it seemed), so I hastily grabbed the CLP and showered it.
It is looking good. Here are the pics of the cz-82 slide after the re-sanding.




Tomorrow: Take 2 for the extractor....

I decided to try the bluing pen and picked one up at Academy last night.  I used it on my surplus 83 that came with a little holster wear.  I was surprised how well it worked!  It matched perfectly and looks new!  I used the finger wipe method in the video link above which I think helps get an even finish.  I repeated some areas until I got a good match.  the unstuctions didn't say anything about prepping but I did wipe down the gun first to remove any grease and oil.  I also bought the whole kit to try on my P-64.  Are most 83's blued?  someone told me it should have been painted like an 82.

To answer a previous question, cold blueing is nowhere near as stong of a finish as hot blueing.  Great 2nd best since hot blueing is expensive.

[Gottmituns]

Absolutely right. Well, now it's not as dark as it was with the first cold blue from yesterday. (It's grey)
I got a bit frustrated since my CZ-82 is my EDC, my pride and joy, my go-to gun. So today I ordered the Duracoat   Aerosol Gloss Black (So I can hopefully match the original glossy black frame my CZ came with).
Since now I am an expert at gun de-bluing, I'll have it prepped and shiny so I can paint it with Duracoat.
I am only doing the slide. 36 bucks for the duracoat.

After stripping my CZ82 slide with acetone and 0000 steel wool I cold blued it and was relatively happy with the result.  For the curing in oil I simply submersed it in a tall thin jar filled with SAE 30 motor oil and let it sit overnight.  It worked great for me, and that jar of oil is just sitting on the shelf awaiting my next small project.  As they say, YMMV.
