What Causes Car Paint to Bubble?
2 Answers
Possible reasons include poor paint quality and improper construction conditions or processes. Below is a relevant introduction: Automotive Paint: Automotive paint primarily serves to protect the car body from corrosion, while also enhancing the vehicle's aesthetic appeal. It is a common way for car owners to express their individuality. Concept: Automotive paint refers to the paint sprayed onto a car, hence the name. It is a type of coating. Applying paint to a car not only forms a protective film on the body surface, making it less susceptible to corrosion and extending the vehicle's lifespan, but also provides a visually pleasing experience. Different automotive paints produce different effects, and choosing different types and colors can showcase the car's unique personality. Therefore, automotive paint is crucial to the car itself.
I found that when car paint bubbles, it's usually caused by moisture getting underneath the paint. Last summer after washing my car, I noticed several small bubbles appearing on the side of the body, which popped when touched—a sign that the metal was starting to rust. The reasons for water penetration might include using a high-pressure water gun too aggressively while washing, parking on damp ground during rainy days, or having small scratches on the body that weren't repaired in time. Over time, accumulated moisture causes the paint to lift, just like skin blistering. If left untreated, it can spread to larger areas, affecting aesthetics and accelerating rust spread. Now, I inspect my car every few months, immediately treating any scratches with a touch-up pen and parking in dry areas. Regular waxing to protect the paint surface can keep water out, reducing the chances of bubbling.
