Just buy a magnet off of Amazon and place it between your phone and case.

This is probably a much more small scale project than most of you are used to, but I used to have a metal-backed phone battery case specifically designed for use with magnetic mounts. That particular case started having some issues that I heard were common for the brand, so I decided to get a new one, but it's not magnetic and I've really become fond of using magnetic mounts. I have a couple metal mounting plates that are supposed to go on the back of the phone, or between the phone and the case, but the magnets don't seem to be quite strong enough when the case is between the plate and the mount. I'm considering moving the plate to the outside of the case to maximize the connection, but I'd like something to cover/protect the metal plate so minimize it snagging on things or just ruining the look of the case.

Does anyone know of anything I could use to basically put a VERY thin rubber-like layer over the outside of my phone case to help with the idea? The first thing that comes to mind is kind of like vacuum-forming a balloon, just to give you a better idea of what I'm trying to do in case my description doesn't help, which I probably doesn't.

Yeah here

So in that case some of those adhesive metal plates online could probably help if there’s something you wouldn’t mind sticking it to.

You can shorten Amazon and some other links by removing unnecessary parts, such as referrals:
