Works for it's intended purpose
I would first encourage you to ignore most of the 1 and 2 star reviews. It's obvious a lot of people don't understand what anodized aluminum is and what this product does. Anodizing is a electromechanical acid bath process. It's not a paint like coating. That being said it can't be repaired with paint. This product is a combination of sulfates and acids and has no color like paint would have. It comes out of the pen or bottle more or less as a clear liquid. It's purpose is to chemically attack the surface of exposed aluminum and darken the surface. It only tries to mimic the appearance of anodizing as you can't repair anodizing, you can only try to minimize the appearance of the damaged anodized aluminum surface. That is what this product does. It's not perfect but it is your best option for trying to minimize the appearance of damage to anodized aluminum.

Wasn't sure what to expect
I'm shocked. I had a small scratch on a Marfione custom knife. Pricey knife with a small scratch that was making me sad. I had tried the black marker trick with some success, but any time I cleaned the knife, or rubbed over the area with my thumb, the marker came off. It was strictly cosmetic and nothing more. After reading another reviewer on here had success on his Microtech knives, I decided to give Aluminum Black a shot. My process was a little different than the instructions, but it yielded amazing results: 1. I first used painters tape to mask around the scratch so I could work and not worry about the surrounding areas. The scratch I was working on was right at the top most part of the knife, so I wrapped the surrounding areas. 2. I applied rubbing alcohol on a cotton swab to prep and clean the area. 3. I used an art-gum to gently remove oxidation from the scratch and brighten it up again. The instructions said use steel wool... I'd never. :p I've used art gums to gently clean electrical contacts on circuit boards in the past, and it did wonderful here. 4. I cleaned the area again with rubbing alcohol on a cotton swab and dried the surface well 5. I applied Aluminum Black... It did... a little something but not much. I had to fight with the surface to remain wet, so I gently just applied Aluminum Black from the pen tip over a 30 second period. 7. I rinsed the area with a wet cotton swab 8. The first application didn't do much. Nor did the second or third. Finally, around the fifth and sixth the area began to disappear. 9. I noticed there was some extra blackening around the area I was working on, run off from the pen. I cleaned the knife, rubbed the entire surface I was treating with my thumb, and buffed the color out. 10. The scratch was now almost completely gone. I decided to do another application, and then a final coat of Aluminum Black. This time I didn't worry about keeping the surface wet, I just let it sit for a minute, cleaned, buffed it with my thumb and repeated. 11. The surface was perfect. I mean perfect. I couldn't for the life of me find the scratch after that last application. I buffed the area a little more with my thumb and then cleaned it with a wet cotton swap. 12. I applied Rem Oil to the treated surface and let it soak in before buffing it dry. I'm blown away. I've scrutinized the area under bright direct lighting, natural lighting, and artificial lighting and the surface looks flawless. I am relatively confident that it will remain that way too. I buffed it well with my thumb and it's not budging, and this makes this otherwise perfect knife completely perfect again. If someone has a Microtech or Marfione knife that is scratched and you want to get it back to black, I honestly cannot recommend this stuff enough. Made a real believer out of me and I'll definitely be keeping Aluminum Black in my drawer for future repairs. Top stuff!

Didn't work for me
20 applications later I just started to lay it on because it wasn't working and it looks worse then using a regular maker. I even listened google AI saying to use a wooden toothpick to drip it in just the bare metal area then wet cloth dap it off then towel dry it before next application this should maybe take 5 coats well I did that 10 times then got fed up and did it another 10 times this time straight from the pen laying it on wet for 1 minute before wet wiping it clean and drying it. Note during the wet wiping it did not lose color it stayed the same never got any darker in any stage of using this product application to clean up.

Works great, but make sure you follow the directions
Used this to work out some of the holster wear on a milsurp I bought. It does work, but you need to follow the directions. Chiefly, the prep instructions. You can't skip the cleaning, de-greasing, and buffing before hand or you will get lackluster results. If you do everything correctly and give it a bit of time to work you should get a darker finish that looks way better than bare aluminum. However, you should note that this is NOT going to make the metal look like an original factory anodized finish, nor is it supposed to. What this means is that larger areas of wear will look dark, but will not 100% match the factory finish. This is NOT a product fault. I really like the fact that this is in the form of a touchup pen. Its way more convenient than busting out the bottle and brushes like I have to do to use cold blue.

Great item for small cosmetic issues.
Great for small touchup areas. With some finesse, makes covered area look like original finish. Seems to hold up decently and not immediately wear off.

It doesn't work as advertised.
Truth be told this product doesn't work very well on its own to mask scratches. While it certainly does help dull some of the marring that reveals the raw aluminum, it doesn't completely erase them like I had hoped. I've found that using a combination of both this product and the Black Overseas Paint Marker works the best to hide a scratch. What I do is I do a couple of passes following the instructions of the Birchwood Casey pen, looping back to the first step after applying the product and rinsing two or three times. Once the scratch stops fading and hits a stopping point in its improvement, I apply very small dabbles of the Overseas Black Paint on the scratch and rub it in with my finger. Then I reapply the Birchwood Casey product and rinse and repeat until I get the desired color. Once I get the color I like and everything dries, I apply a thin layer of oil like Balistol and let it cure overnight. Obviously your mileage may vary. I've successfully gotten rid of two scratches using this method, although it truly does suck how it takes so much extra effort it takes to get rid of a scratch rather than ideally using the product as instructed and be able to fix a scratch in one go. It takes a ton of extra work to get it perfect (as with anything frankly), but it is disappointing that the product hasn't worked as intended with either of my repairs.

Color match
Had a small scar on my Leupold scope. Used the marker to cover the exposed metal. If you don't know where the scar was, you would have a difficult time finding it.

I shouldn’t be buying American right now but…
I shouldn’t be buying American right now, but this little pen seriously came through. Supposed to used on guns but I used it on a nicked corners of my anodized black keyboard case (Tofu60), where the raw aluminum was showing through as bright silver — and it darkened it perfectly. Guns should work fine as long as the raw aluminum is exposed and the colour is anodized black! Just clean the spot with isopropyl, apply it with the pen, let it sit, wipe it down, and optionally oil it up a bit to blend. Would recommend for anyone who gets emotionally damaged by cosmetic scratches like I do.

Worked well, no fuss, no muss, nothing to clean up.
I used the pen to treat some scratches on the aluminum body of my Winchester shotgun and it worked well.

以前の液状の物より良い
表面処理仕上げのVFC製のタッチアップに非常に重宝します。 重ねても塗っても以前の液体容器タイプよりもラフな時間で拭き取り可能
