How Long Does It Take to Repair Car Paint?

Repairing car paint generally takes 2 to 3 days, with a minimum of one day required. It is quite normal for minor scratches to occur during regular use of a car. When scratches appear and damage the paint, the car owner will need to have the paint repaired. Car paint coating involves applying a thin film over the car's paint surface to protect the paint's gloss from fading and to provide a physical protective layer, thereby safeguarding the paint. Macromolecular polymers are essentially individual molecules linked together hand in hand. Due to their strong film-forming properties, they can create a true protective film, which is why most car coating products on the market are macromolecular polymer-based chemical products.
The time required for car paint repair mainly depends on the extent of damage and the process. When I had a door scratch repaired at a 4S shop, it took a full day and a half. First, the old paint layer must be sanded off, followed by applying primer which takes half an hour to dry. Then, the topcoat is applied and requires two hours of baking under a lamp. If the damage reaches the primer and exposes metal, rust prevention treatment is needed first, adding another half day. Color matching is the most time-consuming part—for example, pearl white may need four or five adjustments to eliminate color differences. Including polishing and finishing, the entire process typically takes at least 24 hours. It's best to drop off the car early on a weekday and pick it up the next day.
