Magnetfolie expressly recommends using magnetic signs only on surfaces made of magnetic metals. Not all metals are magnetic! Only iron, cobalt, and nickel are magnetic metals. Since aluminum is increasingly being used in the manufacture of vehicles, you should check whether your vehicle has magnetic surfaces. If your car does not have a magnetic surface, we recommend our car films. These can also be removed without leaving any residue. Please make sure to
always read the accompanying instruction sheet (We include a copy in your package, or you can find it here:
