Will Car Paint Bubbles Disappear After Sun Exposure?

No. Here is the relevant content introduction: 1. Treatment method: Car paint bubbling is caused by inferior paint combined with poor workmanship, where the metal surface wasn't properly treated or rust-proof primer wasn't applied during painting. It should be addressed promptly. Make sure the technician thoroughly sands away all rusted areas before applying a rust-proof primer, followed by color paint. Ideally, a clear coat should be applied over the color paint to ensure durability. 2. Paint maintenance methods: (1) After vehicle use: Promptly remove dust from the car body to minimize static electricity's attraction of dust. (2) Wash the car promptly after rain: Rainwater contains many acidic substances and dust. Rain spots on the car will gradually shrink, increasing the concentration of acidic substances in the rainwater. Combined with dust in rainwater forming rain spots, if not rinsed off with clean water promptly, over time it will damage the car's paint surface.
I found that bubbles in car paint usually don't disappear after sun exposure; instead, they may worsen. Bubbling typically occurs when moisture gets beneath the paint or due to corrosion. When exposed to sunlight, the heat causes expansion, increasing air pressure and making the bubbles grow larger or even burst. This happened once in my old car—a small bubble turned into a large bulge after a few days in the sun, eventually causing the paint to peel off, leaving an unsightly appearance. It's important to promptly check if the issue stems from water leakage during washing or holes caused by scratches—don't delay. It's best to move the car to a shaded area to prevent high temperatures from exacerbating the problem. I recommend taking it to a professional auto body shop for treatment. They can clear the bubbled area and repaint it to maintain the vehicle's appearance and safety. For daily parking, choose shaded spots, and during regular maintenance, pay attention to any changes in the paint to prevent similar issues.
