Why Won't My Magnet Sign Stick? November 06 2025, 0 Comments

Magnetic signs won’t stick to many modern vehicles because more and more body panels are made from aluminium, fibreglass, plastic and other non-magnetic materials.

Models like the Ford F-150, Jaguar XJ, Audi A8, Tesla Model S/X and the Chevrolet Corvette are well-known examples where magnets simply fail. 

Gripper Mats solve the problem by creating a strong, paint-safe, adhesive-free grip between your sign and the vehicle surface — allowing you to use your existing magnetic signs on any panel, even when it isn’t magnetic.
