Can Car Paint Be Repaired on Rainy Days?
2 Answers
Car paint cannot be repaired on rainy days. Below are some relevant details about paint repair: 1. Car paint repairs must first be dried in a baking room before the car can be driven. Otherwise, the wet paint will severely affect the appearance. The baking room is built indoors, so it is unrelated to whether it is raining outside. 2. If you are applying paint manually and relying on natural drying, it is still recommended to do this on sunny days. The reason is: the primer under the paint is putty, and the oil content in the paint is relatively high, making it harder to dry. Rainy days tend to be cooler, slowing down the drying process, so it is advised not to apply paint at this time. If the putty is not dry, the paint may not adhere properly and could bubble. Here are two suggestions for paint repair: 1. Use professional equipment and have the paint applied at a car repair shop—this can be done anytime. 2. If applying paint and relying on natural drying, rainy days can lead to bubbles. It is better to wait for a sunny day before proceeding.
I've been repairing cars for over ten years and often get asked about this. While it's technically possible to do touch-up painting on rainy days, I really don't recommend it. High air humidity significantly slows down paint drying, making it prone to bubbling or water marks. If small roadside shops rely solely on natural air drying, the touched-up paint can easily peel off later. Professional factories with temperature-controlled paint booths can manage humidity and temperature in enclosed spaces, allowing them to work even in rainy weather. However, you must absolutely avoid getting the fresh paint wet immediately after touch-up - new paint needs at least 48 hours to properly cure. If rain washes over freshly applied paint, all your effort will be wasted.
