The time required for painting is divided into the following situations: 1, small area local spray drying: within one day. 2, large area local spray drying: one day. 3. Spray drying of the whole vehicle: it can be used normally for at least two days. The following are the precautions about painting: 1. Choose a better garage: when painting the car, choose a garage with good reputation and good technology. 2. Negotiate the price in advance: If you don't repair the car in the 4S shop and go to other places for plastic painting, you should negotiate the specific price in advance to avoid various disputes after repairing the car. 3. Plastic surgery should be in place: car plastic surgery is more critical. If the plastic surgery is not good, the surface of the car will look uneven, which will greatly affect the appearance.
