What to Do About Paint Bubbles?
2 Answers
Paint bubbles require professional repair at a specialized auto repair shop or a 4S dealership. The cause of paint bubbles is often due to poor-quality paint used for touch-ups, which deteriorates over time, necessitating a repaint to resolve the issue. Paint bubbles can also result from unskilled technicians or improper procedures during the painting process. High standards are required for paint application conditions and techniques. The environment must be dry before painting, and the air hose connected to the spray gun must remain moisture-free. Any water contamination in the system can lead to paint bubbles.
Last time my car's paint also bubbled up, which really worried me. Paint bubbling is mostly caused by moisture or air trapped under the paint layers, such as when the car isn't completely dry after washing or when old paint repairs aren't done properly. You can start by gently cleaning the bubbled area with a soft cloth—avoid strong detergents to prevent worsening the issue. Then check the size of the bubbles: for small ones, you can carefully sand the edges with fine sandpaper and apply a touch-up pen for protection. But if the bubbles are large or you feel unsure, take it to a professional repair shop immediately—they can fix it thoroughly to prevent corrosion from spreading or affecting the car's structure. Usually, try not to park under direct sunlight for too long, and regular waxing can help avoid such problems.
