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

I used this on my wifes gun which had some paint scraped off as well as on my PC case. Both are covered at first glance. On further Inspection the paint is elevated from the rest of the surface, but its a decent low cost cosmetic touchup

Used this on a scratched Holosun Optic, worked great and covered it right up

Good match for small gouges or scratches. Convenient applicator. The only improvement that I would appreciate would be a finer tip. The tip of this pen is like a bold sharpie and limits the detail. Keep a fine brush handy for that reason, otherwise, this is another excellent product from Birchwood Casey and a good choice.

I went to use this pen 2 weeks after the 30-day return time the paint is dried out I could not get it to come to the tip fully to beusable I shook it for 20 minutes no good everyone said it's a good product but I think maybe there's selling some older stock that's no good anymore I called the company they wanted me to return it and all this for this little pen and then maybe they would approve a refund after that maybe so yeah don't buy this product or buy stuff from this company they don't stand by thier products they make it very difficult to get a return for a small amount and you don't even know if you're going to get the return they don't guarantee you're going to get your money back or a replacement it's all up to them

Had some issues with an inexpensive castle nut wrench and scaring of nut and buffer tube. I used this pen and made the mistakes disappear.

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.)

Works great watch a video or two to see how to use it.

EL plumón no funciona a su totalidad, se atasca y no permite pintar las superficies, y después se atasca y se chorrea la tinta.

It is not what i want, i have ordered for what picture was given

It takes some time to wet your tip but you have to be persistent. Once it flows the coverage is decent.

Pen doesn’t work, defective. Followed the instructions to use and get to work if dried out, but there’s no paint flow. Amazon support is useless, considered non-returnable, and they’re no help - complete waste of money. Do not buy! I suspect this will be the case for most going forward - old stock dried out.

This touch-up pen worked out very well for me. I’ve used it over a dozen times now, on different occasions, and it hasn’t dried up on me yet. The paint forms a nice hard layer that sticks well to metal - much nicer than taking a sharpie marker to a scratch. I haven’t had any issues getting the paint flowing after weeks of not using it. The black perfectly matches my airguns. I’m very satisfied.
