Why does the paint of MG 6 fall off with a slight touch?

Bubbling on the exterior paint surface is caused by sun exposure. Gently touching the bubbled area will cause the paint to peel off, revealing the primer underneath. Definition of car paint: Automotive paint refers to the paint sprayed on cars, which is a type of coating. Function of car paint: Applying paint to a car not only forms a protective film on the body surface, making the car less prone to corrosion and extending its service life, but also provides an aesthetic appeal. Different types of car paint produce different effects, and choosing different paint types and colors can showcase the unique personality of the car. Therefore, automotive paint is crucial to the car itself.
With 20 years of car repair experience, I've seen many such cases. The thin paint on the MG6 is primarily due to process issues. Inadequate primer treatment during factory painting or too thin topcoat application can lead to poor adhesion, causing the paint to chip even from small stone impacts. This is particularly noticeable on some batches of bumpers, as plastic and metal surfaces naturally differ in paint adhesion. The most frustrating part is that some 4S shops use cheap spray booths for touch-ups, with insufficient curing temperatures, leading to paint peeling within months. In such cases, I recommend using a professional paint thickness gauge—anything below 80 microns is definitely problematic.
