Standard Vehicle Magnets (Signs, Posters & Displays)

For best results, let the magnet fully bond to your vehicle for at least 12 hours—ideally overnight—before driving. The longer it sits undisturbed, the better the grip, helping prevent it from coming off while in motion.

Your magnet may detach.

Not always. Magnets only stick to steel surfaces, and many newer cars use non-magnetic materials like aluminum or plastic. Even on steel cars, some areas (like the doors) may hold a magnet, while others (like bumpers) won’t. Test your car with a fridge magnet before ordering to be sure.

30 mil is a standard thickness for vehicle magnets, offering good adhesion for typical driving conditions. However, extreme speeds or very strong winds could potentially cause detachment if the magnet is not properly applied or is too large.
