The British museum uses it to protect their ancient armor and swords from rust. I have successfully used it on a two-handed Broadsword I received as a gift. Not a speck of rust on it.
You do beautiful work.
Thank you for your compliment
Honestly, if it's a stainless steel slide, most of the time it wouldn't be around enough moisture to cause any rust issues plus stainless steel will rust, but not nearly as easily as a standard steel. Most people keep their guns very clean, especially if they went through the cost and trouble of having it polished. Wax is typically slick (maybe not the kind you are speaking of), which would obviously cause an issue with operating the gun.
If it's the barrel, I would think/hope that most people keep them oiled well enough that rust wouldn't be an issue anyway and it gets so hot it would likely melt any sort of wax away.
In fairness though... I know nothing about this particular wax either, and it might stand up to everything better.
