I'm thinking about Crystal Serum (either Lite (4 years) or Ultra (9 years)) for my 2022 X5.

Has anyone had this particular coating applied?

- Does it last as long as advertised?
- When it starts to break down or wear off, is there any noticeable effect?

It's in the neighborhood of $500 for Lite and $1500 for Ultra, and obviously it has to be done right (esp the Ultra).
