Quickly and easily mark your use on your vehicle with the magnetic sign doctor on duty. The sign is made of magnetic film and has a thickness of 0.9 mm, so it is significantly stronger than the conventional 0.6 mm thick magnetic signs. The format of the doctor in service sign is 300 x 70 mm, so with a length of 30 cm it is also clearly visible on the car. The magnetic film adheres automatically to metal body panels as a sign and can withstand high speeds. However, please note that the signs must never be bent when using. Before you attach the magnetic sign doctor on duty to your vehicle, the surfaces must be clean and free from dust so that your paint cannot be damaged. After use, the sign must be removed again, with continuous use, dirt would collect underneath and cause corrosion.
