Not sure if I have ever heard of a mop and glow effect, all I can say is I have used a couple of caps of polish in my media for over 40 years and I clean my guns after shooting them. There is no polish on the planet that will withstand bore cleaner. If there is please let me know as I would like to use it on my car
I like my brass polished but in reality a good cleaning is all that is needed and some will even disagree with that.
