I purchased this as a anti seize grease for installing AR-15 barrels. I also found that is works well for protecting electric and car battery terminals from corroding.

Maybe it's the fact that it's really good grease or maybe the Umbrella logo on the lid that makes it cool, I don't know but all I do know is that it works well and has cool packaging so it's a win win for me.

Used it on my ak and my ar to change out their muzzle devices due to living in hell (California).Got this specifically because the umbrella insignia seemed cool

AeroShell is a must have for any proper AR builder. Steel barrel nut and aluminum receivers don't do well over time. This is the proper product, by account of several armorers books and programs I've attended, to use to prevent bad bad scary things from happening. Truth be told, this little bottle will last a long time, and is comforting to know that you used it to build your AR to Colt-Spec...
