I've heard somewhere that the BMW paints have a very thin clear coat (4 microns or so) and that if you buff a new car it will take off that finish gradually.
Can somone chime in on this? Is there are product that work wonders for the paint? Something that bonds with the paint and puts a protective coating so that the paint will look/last longer?
Any dealer who tells you that there is no clear coat on the paint is flat out lying to you (or they're showing a level of ignorance that suggests they should not be in the business). I'd suggest you find a new dealer.
Sealants/waxes to help the car looking great longer, but you'll need to maintain and re-apply them regularly (so yes, you will probably need to polish the car before applying either). There are some nano-coating chemicals (e.g. AQuartz), that some of the detailers on the forums here have tried out, but I don't think there has been too much long term feedback on it yet.
