I detailed my car a few weeks ago and though I would share. I did a one step correction using Menzerna FG400 and then coated it with Gtechniq C1 and EXO V2. Here are some pictures and videos. Follow the link to AutoGeek for more details.
BTW, my brother did his M4 at the same time, it was a double detail.
