Birchwood Casey E & F Super Blue Liquid Gun Blue 90 Ml

This stuff worked much better than I had ever thought it would. I had an old piece that the bluing had completely worn off of. I degreased it with carburetor cleaner. And then used a soft cloth to apply it. This very quickly put on a nice deep blue luster finish. I then gave it a light coating of oil. It turned a really ugly old piece into something very nice looking. I'm not sure I would recommend this for a true collector piece but for my use it is great. It would be great, too, for blueing touchup. I would buy this stuff again and I recommend it. I tried to post a photo but Amazon's rules wouldn't let me as it was a fyrearrm🥺

used on my glock and got rid of the holster wear on the slide with about 2 coats and it looks factory with a bit of blue shine in light that looks nice

I buy a fair number of old garage-sale tools to refurbish. Some of the tools I buy are bare steel, either because they were made that way or because the plating is completely gone. I clean them up, get them functional, and blue them with Super Blue.I can't tell you how many 50 cent pliers, side cutters, crimpers, screwdrivers, etc. I've bought over the years. Tool restoration is one of my hobbies, and sometimes I fix them up just to give them away or donate them. I want them functional but I also want them to look good, and I don't want to spend a bunch of time on them.Most often I'll wire brush the old tool, occasionally finishing them off on the belt sander or with a 4-1/2" flap wheel. I'm going for a smooth finish but nothing too polished. It's a tool, after all, not a family heirloom, and I'm going to use it, not hang it up on the wall. After I've gotten rid of the dirt, rust and pitting, I degrease and use the Super Blue.I usually do 2-3 applications, buffing with 0000 steel wool between each one. When done I wipe the tool down with oil and it's ready for service.I did this recently with some crimpers and side cutters that were part of an inexpensive tool haul. I spent maybe 5 minutes prepping each tool before applying the Super Blue. Once I was done bluing and oiling them, they looked excellent. Not mirror-smooth, but smoother than the factory finish for any of them, and the bluing helped to hide any staining or discoloration.I really like the look of oiled blue steel. While this finish won't be as durable as something like Parkerizing (or even rust bluing, probably) it only takes a couple of minutes to apply. The result is about 75% as good as something like caustic bluing with maybe 10% of the effort. Why mess with boiling lye or sodium nitrate solution when I can dab this on with a cotton ball in a couple of minutes?One thing to keep in mind-- don't dip your parts in the solution to blacken them. If you do dip your parts, set aside a small amount of solution just for this purpose and don't put it back in the original bottle. Dipping parts into the Super Blue will leave behind traces of metal that will begin to degrade its performance. No, I don't understand the chemistry behind this, but I saw it happen for myself. The solution will begin to change color and be less effective at bluing.Instead, use a cotton ball or paper towel to apply sparingly, and if you must dip your parts, keep a portion of the solution set aside just for dipping. This will keep the majority of your Super Blue contaminant-free.I can't say for sure if this is a good choice for a firearm or not (I have no experience with Super Blue in that context), but for a quick and dirty tool restoration, it's perfect. This is my 2nd bottle and I always try to keep some on the shelf.

Nice for touchups

Suffice it to say, but I should have taken a “before” picture. Having said that, bluing tools is really amazing! The process is easy, and there are really easy to follow YouTube videos that walk you through the process. In just a few hours you can make old tools look so much better, and the chemical process is corrosion resistant. If you have older, quality tools, buy this product and follow the videos. The pry bar I feature is one I could have cleaned up even more, but just a few minutes with a wire wheel led to a really nice, smooth finish. This is a simple skill, and when you use a quality product you can restore old metal and really extend its life!

I used this to restore the locks on a buffet built in 1916. The instructions were pretty clear on how to do the process and it worked great. I even used it on the wheels as it turned out they were steel as well. I did this job over a year ago.

Great product and fast delivery

It works. Follow directions and keep repeating.
