Summary
Complaint After removing the transport protection from new vehicles, localized cloudy spots or streaks may appear on the paint surface. These marks are most commonly seen on the hood, fenders, and bumpers and are more noticeable on dark paint colors. Cause Moisture can become trapped under the full transport packaging. This moisture may penetrate the fresh paint, causing the paint layer to swell and result in visible white spots or streaks. Remedy Carefully heat the affected areas using a heat gun or Infrared Paint Curing Lamp. • Ensure that seals and other heat‑sensitive components, including those behind the heated area, are not exposed to excessive heat or damaged during the process. • Set the heat gun to 500–600 °C (932–1,112 °F). • Hold the heat gun approximately 5–10 cm (2–4 inches) from the surface. For plastic components (e.g., bumpers): DO NOT exceed 120 °C (248 °F). The heating process may need to be repeated several times to achieve the desired result. IF heating does not improve the appearance OR the paint structure is permanently damaged and cannot be repaired, the affected component must be repainted.
