Hi all:
As a brief intro - I used to be quite proficient at detailing, inside and out. Life circumstances have left me with little time the last 5-6 years to really keep up with anything. Some of my product knowledge is stuck in the mid-2000s, to be honest, and I haven`t done a great workup on my vehicles since 2012 or so. I still keep them clean and care for them and they look better than most, but the landscape has really changed.
Right now my main concern is a 2011 BMW in Space Grey Metallic. It was purchased with a paint protection package which I surmise to be one of the major sealants/coatings of the day applied by the dealer after a quick polish. I should also mention that it comes with a "paint protection warranty" that`s still in effect - I guess if something like bird droppings mar the finish they polish and re-seal or whatever it takes to correct the damage. Note that I`m not talking about StoneGuard film - it has that too.
It`s first few years it sat in a garage. The last few it`s been a daily driver (which is all I have, and I still care about). It overnights in a garage but spends 60% of week days parked in a commuter train lot so it sees some elements. It`s only up to about 30k miles at this point so is "like new" in many ways.
So far I`ve only thrown P21S/S100 wax (I told you I was in the dark ages) on top of the coating when I have time (which isn`t as often as I`d like). I have switched from clay to one of those prep mitts and it actually makes it happen more often. I have started thinking about things like a polish with something like Menzerna SF4000/4500 to make things pop a little more (I`m accustomed to darker colours that really shine) but I`m also wondering about the original sealant....
So many threads on what coating to use - not so many on what to do with them later
I`d rather the car didn`t come with this, but that`s not something I can go back in time and change. While it isn`t flawless, it isn`t in need of correction, which I why I was only thinking of a pass to `jewel` and then re-seal/coat/wax. Or, do I just leave it alone.
Thanks for reading and for any advice.

- Is this coating just going to wear off slowly like a wax and I can polish and re-seal/wax?
- Is it important to try to identify which coating this dealership used?
- Should I be attempting to remove the original coating through some process?
- Could polishing partially remove it and really make it look like crap? Or are these things durable enough to take a 4000/4500 polish?
- How will I know when the original coating has worn off or failed? Is it going to look a little like failing clear coat? Or will water just stop beading?
- What coating/sealant/wax should I replace it with?
So many threads on what coating to use - not so many on what to do with them later
