Which is more harmful to the car in summer: exposure to sunlight or using a car cover?
2 Answers
Using a car cover in summer is more harmful to the car. Using a car cover in summer: The temperature inside a car cover is higher because the cover traps all the air circulation inside, creating a greenhouse effect that leads to very high temperatures both inside the cover and inside the car. Not using a car cover in summer: Without a car cover, the air inside the car can escape through the car doors, the rear of the car, and small vents in front of the engine. Similarly, wind from outside can enter the car, resulting in relatively lower temperatures compared to using a car cover.
From a practical car usage perspective, prolonged exposure to the sun in summer is definitely more damaging to the vehicle. Direct UV rays on the car paint can cause yellowing and fading over time, while the plastic and leather interiors become brittle and prone to cracking. High temperatures may also lead to electronic component failures or abnormal tire pressure expansion. A breathable car cover can help mitigate these damages, but caution is needed when using one in summer. If the cover is of poor quality or lacks breathability, accumulated rainwater or moisture inside the car can cause mold growth on the interior, rust on the body, or even scratch the paint. Comparatively, sun exposure causes more extensive and lasting damage, as sunlight and heat are constant. I recommend parking in shaded areas or garages whenever possible. If using a cover, opt for a professional, breathable type—don’t compromise the car’s condition just to save effort.
