What Causes Spot-like Paint Peeling on the Hood?

It could be due to localized color difference defects in the paint that were present when the vehicle left the factory, caused by insufficient uniformity during the paint spraying process. Below is relevant information: Automotive Paint: Automotive paint primarily serves to protect the vehicle body from corrosion and secondarily enhances the vehicle's aesthetic appeal, serving as a means for many car owners to express their individuality. Concept: Automotive paint refers to the paint sprayed onto a car, known as automotive paint. Automotive paint is a type of coating. Applying paint coatings to a car not only forms a protective film on the body surface, making the vehicle less susceptible to corrosion and extending its lifespan, but also provides an aesthetically pleasing experience.
When I first bought my car, I also encountered the issue of spot-like paint chipping on the hood. This is usually caused by flying small stones, such as when driving on highways or gravel roads, where rocks bounce up and hit the hood, leaving small dents. Another common cause is corrosive substances like bird droppings or tree sap that aren't cleaned promptly. If left for too long, they can erode the paint, leading to spot-like peeling, especially if the car is parked under trees or outdoors for extended periods. Once, after leaving my car parked in a park for a week, the hood developed several spots due to tree sap. Additionally, UV aging can make the paint layer brittle, leading to spot-like issues over time. For prevention, I make it a habit to apply a layer of protective wax after washing the car. This helps reduce damage from stone impacts and also protects against corrosion. When parking, I try to avoid areas with direct sunlight to minimize UV damage. If I notice small spots, I address them promptly to prevent them from spreading before repairs are needed.
