I'm not really one for polishing a car to death, but i do like to keep on top of the paintwork, especially when i know how much it cost!
I've only ever used Auto Glym HD Wax on my paintwork and evertime i use it the paint ends up with such a smooth finish, and repels water really well.
Here's some pics, their not the best but their off my phone plus it was getting dark.
at that time of night you can really see the great bodyline that runs the full length of the car which is highlighted by the colour of the car.
so i then tucked it away for the night
