I am a 100% complete novice at detailing but really impressed with the job you have done. My Z4 is ruby black in colour and I'm really looking forward to seeing it at its best, and its by reading articles like this, and all the feedback, and links to other websites that I'm building my knowledge and confidence to give detailing a go. First though, I'm thinking of getting a basic detailing job done by a professional and hopefully stay with him and watch how its done for real and see if I can pick up any pointers.
