Is Car Paint Afraid of Sun Exposure?
2 Answers
Short-term exposure to sunlight is fine for car paint, but prolonged exposure can cause some damage. More information on car paint maintenance is as follows: 1. Before using the vehicle: Remove dust from the car body in a timely manner to reduce the adsorption of dust by static electricity on the body. 2. After rain: Rinse the car promptly. The concentration of acidic substances in rain stains on the car body increases significantly after rain, and failure to clean them in time can easily damage the car paint. 3. When washing the car: Ensure the engine is cooled before washing and avoid washing the car under the scorching sun, as dried cleaning agents can easily leave marks on the car paint.
Car paint is indeed afraid of prolonged exposure to sunlight, and I’ve learned this the hard way. One summer, I left my car parked outdoors for two weeks, and the white paint actually started turning yellow. The mechanic told me that UV rays can dry out the oils in the paint, causing the clear coat to oxidize and crack. Stains like tree sap or bird droppings become even harder to clean after sun exposure and can corrode the paint. Now, I’ve made it a habit to park in underground garages whenever possible if I’m leaving the car for more than half a day. If I can’t find one, I use a car cover—preferably one with a UV-reflective coating to block most of the ultraviolet rays. Additionally, waxing the car every quarter really helps; if water beads up on the paint, it means the wax layer is still providing protection.
