Can You Paint a Car on Rainy Days?

No, rainy days have a certain impact on car painting. Here are the precautions for car painting: 1. Check the spraying pressure: Before spraying, you must first check whether the spraying pressure is normal and ensure the filtration system is clean. 2. Inspect the painting tools: Check the air compressor and oil paint waterproof micro-dust separator to keep the paint hose clean. 3. Maintain the cleanliness of the paint booth: Only spraying and baking processes can be carried out in the paint booth. The door of the paint booth can only be opened when the vehicle enters or exits. When opening the door, the air circulation system during spraying must be activated to create positive pressure, ensuring that dust outside the booth cannot enter.
Painting in rainy weather is usually not ideal, and I've seen many cases over the years. Rain and high humidity can prevent the paint from drying properly, leading to bubbling or a foggy, uneven finish. When humidity is too high, the chemical reactions between paint molecules slow down, making it difficult to achieve proper adhesion. If you absolutely must paint on a rainy day, ensure you have a dry indoor environment, like a garage, and use drying equipment to speed up the process. Even then, the results may be subpar—it's best to wait a few days after the rain stops. Additionally, paint fumes linger longer in humid conditions, which can be harmful if ventilation is poor. Car surfaces are particularly sensitive; painting in damp conditions can lead to peeling later on, making repairs more costly and time-consuming. Unless it's absolutely necessary, I recommend avoiding rainy days for painting.
