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.

MG6 owners in the group chat often discuss this issue too. We concluded it's a result of cost compromise. This car has a sporty positioning but isn't priced high, so the paint process might have been downgraded. Look at Japanese cars in the same price range - their electrocoat layer is much more solid, at worst you'll get scratches but not entire chunks peeling off. Even auto painters nowadays complain that the factory clear coat is too brittle - a slightly aggressive polish can wear right through it. If your new car is like this, hurry to the dealership and have them do an adhesion test. Within the warranty period, you might be able to get a full respray.

Paint layer structure issue! Normally, car paint consists of the electrocoat layer, primer layer, color coat layer, and clear coat layer from the inside out. Missing one layer reduces protection. The MG6 might have skipped the primer layer or the electrocoat layer thickness is less than 0.1mm. Additionally, high-pressure water guns at car washes blasting directly at seams can cause water to seep into the paint layers over time, leading to bubbling and peeling. My advice is to avoid alkaline car wash solutions and promptly dry any water accumulated in the seams after washing.

Just helped a fellow car enthusiast with this issue last week. Here's a down-to-earth method to check: Gently apply clear tape to the paint surface and peel it off. If it brings off paint particles, it indicates a process defect. This commonly occurs in hard-to-spray areas like door handle recesses and wheel arches. Repainted areas are more prone to peeling due to the lower hardness of aftermarket paint. For daily parking, it's advisable to stay away from trees as tree sap and bird droppings are highly corrosive to paint. Best to apply a silicone-oil-based wax monthly to create a protective barrier against corrosion.
