How to Deal with Paint Bubbles?

Use a grinding wheel to sand the areas where the paint has bubbled and rusted. After that, repeatedly wipe the sanded areas with a damp towel to keep them clean and prevent dust. Then, use sandpaper to sand the areas again. Next, apply putty paste. Let it sit for a while, and after the putty paste hardens, sand it again with sandpaper. Finally, cover the surrounding areas of the car and apply a layer of primer. Once the primer is dry, spray the prepared topcoat over it.
When encountering paint bubbling issues on my car, the first thing that comes to mind is that it might be caused by moisture accumulation or underlying corrosion. You need to carefully inspect the size and location of the bubbles—small bubbles have minimal impact, but large areas can damage the car body. For treatment, start by thoroughly cleaning surface dirt, then gently sand the bubbled area with fine sandpaper until smooth. Apply primer and wait for it to dry completely before touching up with matching car paint. The entire process requires patience; avoid sanding too hard to prevent deep scratches that could damage the metal. Untreated bubbles can spread, leading to moisture and rust on the car body, which would be troublesome. It's advisable to visit a professional auto repair shop where they have the proper equipment to handle it thoroughly. After washing the car, ensure it's completely dry, and avoid parking in damp environments to minimize the occurrence of such issues.
If the car paint has bubbles, don't panic—you can try fixing it yourself. First, gather the materials: sandpaper, cleaner, and a touch-up pen or spray can. I usually wash the car thoroughly, especially around the bubbled area, then dry it and carefully sand the bubble smooth—be careful not to sand through the paint. Next, apply a layer of primer and let it dry completely, which might take half a day. Finally, spray the paint evenly and wait for it to cure. This saves money and time, but the result won't be as good as a professional job—you might notice color mismatch or uneven texture. Wear gloves and eye protection to guard against dust and debris. If there are too many bubbles or they're in critical areas like door edges, it's better to visit a repair shop—DIY risks are higher. Regularly wash and dry your car to prevent dirt buildup.
