Works like a charm for covering up scratches and other blemishes on aluminum finishes like upper receivers. A small drop of this stuff goes a long way, and the small bottle size improves longevity. An absolute essential for people with metal airsoft guns or real guns with aluminum components. I've only used 1/10 of the bottle, and even that was worth the full price in my book. It's easy to store and use as well. I used this to cover up blemishes on several airsoft GBB pistols and to hide completely the ugly white text on the side of my umarex hk45ct. It was a fun project and remarkably easy to get done with this product.

I’ll be honest. My expectations were extremely high on this product, and I somehow felt that was true when I hit purchase. I got it, slapped some on my gun with aluminum exposed, and felt a little let down from it not matching the surrounding blacks. So I kept using it a bit more and it definitely stacks the bluing affect if you don’t rub it off with abrasive cotton or paper towel. You have to dabble it and let it dry without blowing on it. If you’re looking to fill a precise gap made from a scratch, this stuff still can do it if you have the minimal patience it takes (~5 mins per 1/2”^2). For that reason, it blends well on other existing paint. Meaning no “ridges” are seen. Is the black not going to match? Probably. But you know what you probably aren’t going to do? Cerakote it again or even for the first time, following a low maintained finish. Just buy this stuff if you want a quick fix that seriously is “good enough” since it mutes the silvery tone made from exposed aluminum completely. If you want a brand new cerakote finish, maybe you should start with all of the other supplies to do the entire finish correctly, paired with the work and time to do it. But in my opinion? This stuff is magical. It doesn’t rub off when it’s done essentially corroding the surface layer of aluminum into black. Granted, it still can with abrasives; it most definitely is not as easy to rub off as when it was actively working. After that though, i would confidently state it’s about 80% as hard to scratch again as normal solid paint in a new spot. Highly, highly recommend.

Works as intended — Was cheaper here than local walmart.
