2 Answers
Peeling car paint can be repaired by following these steps: 1. Clean the surface of the car paint and ensure it is thoroughly dry; 2. Remove the peeling portion of the paint; 3. Reapply the paint using the required coating method and materials. The causes of peeling car paint include: 1. Poor surface treatment of the paint, contaminated by wax, grease, water, or rust; 2. Failure to use a metal surface treatment agent on steel or aluminum surfaces or using the wrong type of treatment agent; 3. The surface temperature of the substrate being too high or too low during spraying; 4. Improper application of primer, use of the wrong type or poor-quality thinner; 5. Excessive pressure of the compressed air.
Last time when the paint on my car roof started peeling, it really worried me. Here's how to handle it step by step: For small areas, you can first sand off the lifted paint edges, gently smooth them with fine sandpaper, clean the area thoroughly, then apply a thin layer of touch-up paint paste. After it dries completely, wax and polish it. If the area is large or the primer is exposed, you'll need to take it to a professional shop for a repaint—they'll sand off the entire peeling section, fill it with putty, then spray primer, color coat, and clear coat in three layers, finally baking it in a drying booth. Remember to wash your car frequently during rainy seasons, promptly clean off tree sap and bird droppings, and regular waxing can also slow down paint aging. Oh, and color mismatch after touch-ups is quite common, with lighter colored cars being relatively easier to handle.
