Why Magnetic Signs Don’t Stick to Aluminum Vehicles

Aluminum is non-magnetic, which means ordinary magnetic vehicle signs simply cannot grip to it. This is a widespread issue across many modern vehicles — especially pickup trucks, electric vehicles, and luxury models that rely on aluminum for weight reduction.

This commonly leads to:

• Signs falling off
• Wasted time and money
• Failed adhesive experiments
• Confusion about why magnets “suddenly stopped working”

Gripper Mats™ were created specifically to solve this problem.

The Gripper Mats™ Difference

Alternatives that try to "copy" our Gripper Mats™ technology, use inferior quality and thinner material. These are a false economy and sadly damage the brand we work so hard to uphold. Other methods of adding signage to your vehicle either involve using static cling which does not last as the static wears out or permanent vinyl decals. Neither of which have the many benefits that Gripper Mats™ offer.

Gripper Mats™ create a reliable bond between your vehicle and your existing magnetic sign, allowing secure attachment without damage, residue, or consumables — and without ever wearing out.

Specifically Designed for Aluminum & Non-Magnetic Vehicles

Including Many Popular Pickup Trucks, EVs & Luxury Cars

Many modern vehicles use aluminum, plastic and composite body panels — which is why standard magnets won’t stick.

Gripper Mats™ vs Adhesive Alternatives

Many online alternatives use adhesive — but adhesive is:

• Likely to damage paint
• Often single-use

Gripper Mats™, by contrast, are a professional-grade, reusable solution.
