What Makes Our Car Magnets Durable?
Our 30mil vehicle magnets are made from high-strength magnetic sheeting designed to adhere securely to flat metal surfaces. The thick, weather-resistant construction ensures they stay put at highway speeds, while the UV-resistant finish protects your design from fading in the sun. Rounded corners help minimize wind lift and make installation safer and more secure. With proper care and placement on clean, dry surfaces, your custom car magnets can last for years without damaging your vehicle’s paint.

Important Note About Vehicle Compatibility
Please note that some newer vehicles, especially trucks and luxury models, are made with aluminum body panels. Magnetic car signs will not stick to aluminum or non-magnetic surfaces. Before placing your order, we strongly recommend testing your vehicle with a common refrigerator magnet to confirm magnet compatibility. Also be sure to remove the car door magnet while going through car washes. Dirt Cheap Signs is not responsible for magnets that do not adhere due to non-magnetic vehicle surfaces, and refunds cannot be issued for this reason. Always test before ordering to ensure proper performance.
