How to Deal with Paint Bubbling After the Warranty Period?
2 Answers
The method to deal with paint bubbling after the warranty period is: remove the bubbled paint area, apply anti-rust treatment, then fill with putty, wait for the putty to dry completely, sand it smooth, and finally spray the car paint. If paint bubbling occurs, it may be due to paint quality or issues with the repainting process, which can be addressed through negotiation and claims. However, it is best to have it inspected at a professional repair shop or 4S store and handled by professionals. Besides external impacts and body quality issues, paint bubbling on car doors can also be related to extremely hot or cold weather, as extreme temperatures can cause the body to expand and contract, leading to paint peeling. Always pay attention to driving behavior to avoid scratches and impacts.
I've been driving for over a decade and often encounter paint blistering issues, especially after the warranty expires as the car ages. Blistering may stem from underlying rust or moisture penetration, occurring more frequently in humid areas. Here's how I inspect the blistered area: gently lift a small section with a knife to check for rust or dampness inside. If rust is present, it must be addressed promptly; otherwise, corrosion can spread and compromise the entire body. DIY repairs carry risks – a basic approach involves sanding the area clean, applying rust-proof paint, then filling with repair paste. However, for large or complex cases, I recommend professional assessment at a repair shop, with costs ranging from hundreds to thousands. Prevention is crucial: apply waterproof wax after regular washes and avoid parking in water-prone areas. Never ignore small blisters – delaying repairs can double costs and impact resale value.
