Yes, our custom car magnets adhere to most vehicles, but it will depend on the surface of the car.
More and more car manufacturers are changing how they manufacture vehicles to make them lighter—replacing traditional steel components with lightweight materials such as aluminum, fiberglass, carbon fiber, and plastic.
Our magnets, however, will only stick to magnetic metal surfaces:
- Stainless Steel (some stainless steels are magnetic and some not)
Depending on conditions they can last 2 - 3 years..
We recommend sizes 4" x 4" or larger for outdoor use. Smaller magnets sometimes have trouble adhering due to the small surface area.
Please note, for use on vehicles to guard against moisture and dirt buildup between the magnet and the metal surface (particularly on outdoor applications), the magnet needs to be removed at regular intervals. Clean both the magnet and metal surface with mild detergent; wipe with a soft cloth or allow to air-dry. (For vehicle-mounted signs, remove and clean DAILY.)
