Can a Car That Has Just Been Painted Be Exposed to Rain?

A car that has just been painted should not be exposed to rain. Below are specific details about car painting and how to handle it if it rains: Condition of the freshly painted car: If a car that has just been painted gets rained on, find a sheltered place as soon as possible to prevent further damage to the paint. Once the paint has dried, take the car to a 4S shop or a reputable repair shop. Use 1500-grit sandpaper with a sanding block and water to grind away the water marks, then proceed with the polishing and waxing process. During the painting process: Stop painting immediately and move the vehicle to a dry location. If only the base coat has been applied without the clear coat, the water marks can be sanded off before repainting. If the clear coat has already been applied, do not repaint; wait for it to dry, then sand and repaint.
I just learned during car repair that rain poses a big risk after painting. Before the paint cures, rainwater can cause bubbles, watermarks, or loss of gloss, affecting the appearance and potentially requiring a repaint. Typically, water-based paints take 24 hours to dry completely, while oil-based paints require over 48 hours. Rainwater contains impurities that can easily seep in and damage the paint layer, so it's best to park the car in a garage after painting to avoid outdoor exposure. If it rains, use a high-quality car cover for full protection. A fellow car enthusiast once ignored this and got caught in the rain, resulting in surface bubbles that cost more to fix to restore the original condition. So, patience while waiting for the paint to dry is key—don't skip this small step to ensure the new paint is perfect and long-lasting. Remember, the first day after painting is crucial—avoid any contact with water.
