Of course, the repair shop will spray the whole door. First, it can prevent the local color difference from being too large to be completed. Secondly, you can earn more. The photo is not good, I can't see it clearly, and there is no reference. I wonder how big it is. This kind of flaky injury is not easy to handle. If you just rub the paint of another car, it's ok to treat it. If you drop your lacquered watch, you will be in trouble. It's not easy to see clearly. Anyway, I don't think you can handle it yourself. If the injury is not deep, find a beauty salon to mend it. If the area is not large, and you are not too particular about it, it is not impossible to drive with injuries, at least it is a warning.
