Why Does Car Cover Leakage Cause Paint Discoloration?
2 Answers
Car cover leakage causing paint discoloration may be due to the cover fading. Below is extended information about paint protection film: 1. What is Paint Protection Film: Paint protection film is a high-performance, eco-friendly new film widely used in the automotive beauty and maintenance industry, commonly known as a transparent paint protection film. It has ultra-strong toughness, and after application, it isolates the car paint from the air, providing long-lasting protection. 2. Material Composition: Paint protection film is a thermoplastic polyurethane film (TPU) containing UV-resistant polymers, is anti-yellowing, has ultra-strong toughness, is wear-resistant, does not yellow, is easy to apply, resists collision and scratches, and after application, it isolates the car paint from the air, protecting against acid rain, oxidation, and scratches, providing long-lasting paint protection.
My car cover leaked and caused the paint to turn yellow, which was quite annoying. The main reason was that the car cover wasn't sealed properly, allowing rainwater to seep in and stagnate on the paint surface. The water trapped there for a long time reacted chemically with the clear coat of the paint, causing oxidation and gradually turning the color into rust-like spots. Ordinary car cover materials like plastic don't absorb moisture; instead, they trap water vapor. This water also brings dust or impurities from the air, fostering mold or moss growth in the damp environment, as if the paint developed spots and discolored. Worse, in summer, the sun heats the water, accelerating corrosion of the paint's underlayers and speeding up the discoloration. It's advisable to choose a rainproof car cover made of breathable fabric—avoid the cheapest options—and park in well-ventilated areas to prevent water from pooling on the roof, saving you the high cost of repainting.
