You could ask the people at the place where you had the test carried out. They will point out the area. Second, you could go over to any of the garages in Sinaiyah which do denting and painting work and they "may be" able to identify the problem area. Thirdly, take your car over to the maroor located in the industrial area. There they may override the objection if the fading away of the paint is minor and allow the istimara to get renewed which can be done there.
