How to Make Magnetic Signs Stick to Aluminum Vehicles (Without Adhesives)

If you’ve tried attaching a magnetic sign to an aluminium vehicle, you already know the result: it won’t stick. Aluminium doesn’t respond to magnets, which makes traditional magnetic signage ineffective.

Some people turn to tapes or glues, but these often leave residue, damage paint, or fail in heat and rain.

Gripper Mats™ offer a different approach. When placed behind a magnetic sign, they create a high-friction surface that grips both the vehicle panel and the magnet. The sign stays firmly in place — even at motorway speeds — and can be removed whenever needed.

There’s no adhesive, no curing time, and no permanent change to the vehicle. Just clean, press, and go.
