| Orange Peel
In the mass production environment, it is nearly impossible to eliminate orange peel. Every manufacturer allows some, but those such as Lexus, Mercedes, and BMW allow less in their specification. In a factory there is no "custom" work or several thin coats applied. It gets sprayed by robots, inspected, judged good or bad, then out the door. Most factory orange peel is from excessive film thickness for a single coat of paint. Remember, it gets sprayed once, and the final film thickness must be met with that 1 coat, so it is usually too much. To the factory, the main concern is corrosion protection. They must meet the required thickness first (with 1 coat), then get the appearance the best they can after that. They usually have the spray technique and paint mix perfected since the paint companies have onsite specialists to take care of this aspect, but orange peel cannot be prevented entirely.
