Birchwood Casey Fast-Drying Fast-Acting Presto Gun Blue Touch-Up Pen for Restoring Scratched and Worn Areas, 1 Count (Pack of 1)

I bought this to touchup a few scuffs on an old 22 pistol that my grandfather gave me. It worked like a charm. I don’t think I would recommend it for large areas but for small bits it’s perfect.

I installed new sights myself on my LC9 that didn't fill the dovetail joint all the way. Had about .010 of the base of the joint on each side of the front sight still exposed and the coating was very light under the original sight. Probably due to the original sight being installed then uninstalled which is normal. Also on the front sight, before installing the new sight, I had to clean up the front and rear "sharp" edges of the joint ever so slightly before installing the new sight. About .005 on both front and rear. Against that black of the slide, that silver stood out like a sore thumb! There was no damage, just the coating was worn. I looked on YouTube for a solution and saw this pen. So I tried it and it worked perfect!!! I cleaned only the area missing the coating with a cue tip lightly moistened with some acetone (wife's finger nail polish remover lol, same thing) very well. Let dry for a minute or so then used the pen. I went over the silver lines about 5 times letting it dry for a minute or so before each application. I also used a "NEW" soft bristle brush I bought from Harbor Freight (about a buck) every couple coats to kind of blend it a little. It was about 99% perfect. I don't think anyone else would of really noticed but me, but when I took a cleaning patch with a dab of gun oil and wiped it down even I couldn't see it anymore. I took another patch (no oil this time) and wiped the area as to get as much oil off as possible and it was absolutely perfect!!! Nothing came off and I couldn't even tell where I did the touch up. I really tried my best with a couple more clean patches to wipe it off and it still looked great. I see that some reviewers didn't have the same experience as I did and I was on the fence about buying this, but I'm glad I did. The job came out so great except for those darn lines that really bugged the heck out of me. Anyhow, problem solved!

Was skeptical about cold bluing. Tried it on a scratched handgun. Am satisfied with results and was simple application.

This bluing pen did a nice job.

This is a must have to use when needed. I bought a Glock 30SF and only had the gun for a week. In that week I was trying to find the right holster and the first holster I bought literally scratch my brand new gun within the first 5 minutes of using the holster. The new Glock slide finish scratches super easy it seems, so I bought this blue pen based on YouTube reviews. Although my scratches were fairly small and not bad, but they were scratches that I didn't want to see. This pen fixed all the tiny scratches and I'm super happy with this product. It worked for me and the scratches are all gone. You cannot tell there were ever scratches it worked like magic. Definitely a must have for your gun supplies.

I bought some Birchwood Casey bluing in a bottle a few weeks ago- to touch up some scratches I put on the slides of a few pistols that I installed Tritium sights on.. I was disappointed with the results. THIS pen, is completely different. It literally erased all the scratches and 'rubbed off' areas on my Walther PDP, Canik METE SF, and both Grand Power Q series slides. Amazing product, and incredibly easy to use. It worked right away, too. I was pleasantly surprised. Excellent!

It made the scratches I was trying to conceal look even worse than before. I do not recommend this.

I restored four Glocks and a rifle with it. Scratches and holster wear disappear.

Very useful pen. I scratched the barrel of my new handgun Browning Buckmark when I tried to remove it. I was very frustrated for my bad luck. So I read about the pen and its positive comments. And I decided to try. After reading the instructions I simply used the pen. Fantastic no scratch appears now. I highly recommend this gunsmith tool.

Works great on small worn spots on steel barrels and receivers. Wipe it on and watch it darken, great stuff to help keep your firearms in rust free condition longer.

Wow, just wow! A product that works as advertised. My expectations were exceeded. I did a redneck gunsmith job with a dremmel and this stuff made it all look professional. I highly recommend.

Merci

Works surprisingly well on small scuffs and scratches on flat black guns. Apply several light coats to scratch only, wiping with a soft cloth in between. Do not expect to blue large patches or for that matter small patches; this is not what it is intended for.
