Bubbles on car paint will not disappear after exposure to sunlight. Below is relevant information about bubbles on car paint: Treatment methods: Bubbles on car paint are caused by inferior paint and poor workmanship, such as improper treatment of the metal surface or failure to apply anti-rust primer during painting. It should be addressed as soon as possible. Ensure that the technician thoroughly sands down all rusted areas before applying a layer of anti-rust primer, followed by the color paint. Ideally, a layer of clear coat should also be applied over the color paint to make the paint more durable. Paint maintenance methods: After using the vehicle: Remove dust from the car body promptly to minimize the adsorption of dust due to static electricity on the body. Wash the car promptly after rain: Rainwater contains many acidic substances and dust. The rain marks on the car body will gradually shrink, increasing the concentration of acidic substances in the rainwater. Combined with the dust in the rainwater forming rain marks, if not rinsed off with clean water in time, the car's paint surface will be damaged over time.
I've been repairing cars for twenty years, and to be honest, paint bubbles caused by sun exposure definitely won't disappear on their own. Just recently, a Highlander owner believed in a folk remedy and left his car outside in the scorching heat for a whole day. The result? The bubbles swelled up to the size of coins! This happens because bubbles are caused by rust or moisture trapped beneath the paint layer. When exposed to the sun, the moisture inside expands even more. Even if the surface dries out, the underlying metal is already corroded, and the only solution is to sand it down and repaint. Don't take the risk—if you see small bubbles, get them fixed immediately. Otherwise, the repair costs later on will really hurt your wallet.
