I wouldn't worry too much about orange peel. One time i came across a thread in a mercedes forum about a guy complaining not just of orange peel but also a small unpainted area in the rear fender of his R230 SL55. Normal na siguro iyan unless we're talking of the $300,000 Maybach or Bentley Arnage Mulliner which are suppose to be manually painted with a dozen or so coatings of paint.
