SummaryHyundai applies a Paint Protection Film (PPF) on new vehicles before delivery to dealerships. It provides a barrier between the paint and contaminants, such as rail dust, acid rain, and industrial fallout. In rare cases, the paint can become clouded under the PPF. These spots are the result of moisture trapped between the PPF and the paint.
