What is "orange peel" in automotive finishes?

Orange peel refers to a specific surface texture that resembles the bumpy skin of an orange. It typically occurs when the application of paint is not executed with the correct technique. Factors contributing to this condition include improper spray patterns or inadequate gun settings, leading to the paint not flattening out as it dries. In essence, orange peel is a result of the paint's inability to achieve a smooth, even finish during application.

The texture is generally a result of the paint droplets being too far apart when sprayed or the paint drying too quickly before it has a chance to self-level. This flaw is undesirable as it can affect the overall aesthetics of the automotive finish, making it appear less professional. Proper spray technique, including the right distance from the surface, adequate overlapping of passes, and appropriate nozzle size, helps in mitigating this problem and achieving a smoother finish.
