How to Deal with Car Paint Bubbling?
2 Answers
If the bubbling area of the car paint is small, you can choose to touch it up with the same color paint. If bubbling occurs in multiple parts of the car body, the best solution is to repaint the entire car; otherwise, it will significantly affect the car's appearance. Here are some related car paint maintenance tips: 1. Wash your car regularly. Relying on rain to clean your car is a misconception, as the impact of rainwater on the paint accumulates over time. Initially, it may seem harmless, but prolonged exposure will accelerate paint damage. The correct approach is to rinse your car after rain and wipe it dry. 2. Waxing, glazing, and paint coating can effectively protect the car paint. 3. If substances like asphalt, bird droppings, or chewing gum stick to the paint, clean them off promptly to prevent further corrosion.
With over a decade of car repair experience, I've dealt with numerous paint bubbling issues, usually caused by rust or poor painting. If not addressed promptly, small bubbles can grow into large ones or even expand rusted areas. The steps are straightforward: first, clean the bubbled area to ensure it's dust-free; then carefully sand the bubbles off with medium-grit sandpaper until the metal surface is exposed. Remove any rust thoroughly. Next, apply a layer of primer, let it dry, and then spray matching paint in thin, multiple coats to prevent runs. Finally, fine-sand and polish to restore the gloss. DIYers should wear gloves and masks to protect against dust. A touch-up kit online costs just a few dozen dollars, but for large bubbles or deep rust, it's better to visit a professional shop—saving time and ensuring durability. For prevention, avoid parking in the rain and regularly waxing the car paint works well.
