Does Rain Affect Car Painting?
2 Answers
Rain does affect car painting. The main reasons and precautions are as follows: Main reasons: It is best not to choose rainy days for car painting because the paint surface is not easy to dry thoroughly in humid weather. Even if it is dried for a long time after baking, such a paint surface is prone to gloss degradation over time. Precautions: Be careful not to let the newly painted areas come into contact with water and dust. It is best not to drive out on rainy days because the newly applied paint is still tender and may leave marks when exposed to rain, which can be unsightly and sometimes cannot be removed by polishing. It is best to park in a garage at night. As for sunlight, there is no need to worry, as it will only speed up the drying of the paint, which is beneficial without any harm.
I've seen quite a few car repair cases where painting a car on rainy days is definitely not advisable. High humidity causes the paint to dry unevenly, often leading to bubbles or cracks, making the finish look wrinkled and ruining the aesthetics. Even worse, moisture mixing into the paint layer results in poor adhesion over time, making it prone to peeling. When I helped a friend with a job once, we insisted on painting during rain, and it turned into a mess—the paint wouldn't dry properly, forcing us to sand it down and repaint. So, it's best to wait for dry weather or work in a garage or paint booth where humidity is controlled. Remember, be cautious when humidity exceeds 60% in the air to avoid wasted effort and extended repair time.
