Works just about perfectly for what it was designed to do. Makes small touch ups easy to do.

Used it for some newb first timer scratches on my blued 1911. Did a great job covering them up. Easy to use, works and quickly. I'm far from a gunsmith, so this is a great product.

I read some of the negative reviews and discounted them bc of how many positives there were. MISTAKE! It was a waste of money.The product has a felt tip that hardly releases any chemical. My pen was practically dry. Did not do anything to touch up the scratches I was hoping to cover. Went for quick and convenience and just threw away $16.Don't do it. Avoid this pen product. It does not work. Listen to these 1 star reviews.

I was apprehensive about how well this would work, but I got a decent scratch on a parkerized barrel and needed to try something. This product filled it in almost perfectly, you have to look really hard in the right lighting to see where the scratch was. Not sure how well this would work on blueing, but it matches military finishes. I wish I would have taken some before and after pictures to show how well it worked.

When I first took it out the package, the felt tip of the pen was dry as a bone and bright colored; not the blackish blue color I expected. I thought it’d be the same color as a sharpie because the pen looks the same. However, after repeatedly tapping the felt tip against the problem areas of my gun, until a clear colored liquid came out in small amounts -several applications later, the silvery scratch marks on my Sig Sauer P365 due to falling on a pavement, are now virtually gone. Give this thing a chance!!! I kept attempting to return it thru Amazon and they made it hard as hell, so I decided to accept my loss of 14 dollars. At that point I kept toying with it and what do ya know..the sun of a gun works!

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.

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 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.

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!
