*Surface CompatibilityEnsure that the surface of your vehicle is suitable for adhering a magnet. Magnetic signs and decals work best on flat, smooth, and metallic surfaces. Avoid applying magnets to non-metallic, textured, or curved surfaces as they may not adhere properly.
**Vehicle MaterialConfirm that your vehicle is made of ferromagnetic materials such as steel or iron. Magnets do not adhere well to non-magnetic materials like aluminum or plastic. If your vehicle is not magnetic, consider alternative methods for displaying signs or decals.
