Birchwood Casey Long-Lasting Fast-Drying Super Black Touch-Up Pen for Deep Scratches and Worn Areas, FLAT BLACK, 0.33 OUNCE

This pen is perfect for touching up small scratches on metal surfaces. It goes on smoothly, dries fast, and the black color blends in well with factory finishes. I used it on a few scuffed gun parts and it made them look almost brand new. The tip allows for precise application, and the finish holds up over time. Simple, effective, and very easy to use—highly recommend for anyone needing quick and clean touch-ups.

Nice

Birchwood Casey Super Black Touch-Up Pen is perfect for covering scratches on blued steel and black knives. Fast-drying, long-lasting, and super easy to use—my go-to for keeping blades looking sharp and flawless.

Great little paint pen it really does well matching factory finish on an ar15 super nice if you need to touch up areas on your bang toys and like it says it really is super black

Awesome pen. Used to patch up part of my receiver. Make sure you choose the right one (gloss vs flat black). The material will protect exposed surfaces. Can be removed with enough elbow grease, but will hold up if the patched area isn't subject to extensive abuse. The applicator tip has a tendency to fall out, so just make sure you have the cap on when shaking it before you apply it.

Does not last on metal.

I had several scratches on my firearm barrel assembly and this touched it up perfectly. I realized that you need to use it sparingly or it dries a little off. The first use, I used too much, and cleaned the excess off with some oil. Looks great now. I would advise that you make sure what you are using this for is indeed matte black, or as close to matte as possible, or you might run into an issue with the color matching perfectly. If you are using this on something that is indeed matte, use sparingly, and you will be pleased.

More than 10% of the reviewers could not make the pen work and assumed it was dry or empty. I thought exactly the same until I figured out what's going on: the tip of the pen is just a wick (that you can easily pull out if you want), the pen is a reservoir of paint with a metal ball inside to agitate the paint. When you press the wick into the pen it opens a valve behind it and the paint is supposed to be wicked out. The problem is the paint is very think and it takes a LONG time for the paint to start flowing into the wick and travel all the way to the tip. It might also be the case that the valve came partly blocked, I don't know. In any case here is what I did: First I tried their instructions several times with no effect -- the entire wick stayed immaculately white. Since the pen is not returnable, I decided to be a bit more forceful: I held the pen vertically with a loose fist and I let it fall on its tip on a piece of paper from 3-4 inches up maybe twenty times. At this point when I took the wick out it finally showed some black paint at its base. Woohoo! So then I just held the pen pressed down for couple more minutes until the wick was fully saturated all the way to the tip. I used it to restore an ancient (50+ years old) photo lens leather case. You can see in the before picture that it had a hinge held with some metallic rivets and the paint on the rivets was worn out. I just painted them over, without any surface cleaning. I didn't really wanted them to look new either so the result is perfect for me. If I wanted them to look newer and shinier I would probably clean the old paint to bare metal, but I am not sure how much better is possible. (In the "after" picture the leather was cleaned and waxed as well, but this has nothing to do with the BC pen.)
