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.

Worked as described. It took a little longer than I expected to start working, but put a beautiful black patina on my shiny aluminum knife scales. Happy with the results. I wore gloves and tried to avoid touching the product, but I do wonder if it should come with more instructions than the generic safety warnings on the bottle. Take that advice as you choose. I found a Qtip to work better than a cotton swab since it gave me a handle where I didn't have to get the liquid on my gloves.

Works great. Easy to apply.
