Birchwood CaseyFast-Drying Fast-Acting Aluminum Black Metal Finish Touch-Up Pen for Restoring Scratched and Marred Areas

Works as described. I used it on my Holosun SCS and it blended right in. So then I used it on a lower receiver and had similar results. I think it works great on a matte black finish.Pen also came fresh, not dry.

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 well5. 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 swab8. 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!

Bought this item and went to use it and the touch-up pen was totally dry. I tried to return it since it was obviously defective but Amazon said it could not be returned. When I shake the pen it's totally empty so not a clogged applicator.
