Is it okay to paint on cloudy days without sunlight?

From a theoretical perspective, it is not recommended to perform painting in such weather conditions. Of course, you can proceed if it's just cloudy without rain, but the paint will dry more slowly after application. Introduction to Automotive Paint: Automotive paint refers to the paint sprayed onto cars, known as car paint. Automotive paint is also a type of coating. Functions of Automotive Paint: Applying paint coatings to a car not only forms a protective film on the body surface, making the car less susceptible to corrosion and extending its lifespan, but also provides an aesthetically pleasing experience. Different automotive paints produce different effects. Choosing different types of paint and colors can showcase the unique personality of the car. Therefore, automotive paint is crucial to the car itself.
Spray painting on cloudy days is indeed feasible, and personally, I find such weather quite suitable for this task. Without direct sunlight, the paint won't dry too quickly, which helps prevent bubbles or dust from sticking. However, the key factor is the humidity level. If the air is too humid, the applied paint may turn white or develop watermarks, resulting in an uneven surface. Therefore, I always check with a hygrometer first—ideally, humidity should be between 50% and 70%. If it's too humid, I either wait or find a well-ventilated area, preheat the car, and clean any surface grease before spraying. Additionally, wearing a mask and ensuring good ventilation during painting helps the paint layers cure more evenly. After spraying, avoid touching it immediately—wait a full day for it to dry thoroughly to prevent future peeling. In summary, cloudy days are a viable option for spray painting, just avoid doing it during heavy rain.
