Proper Design Gripper Mats™ magnetic sign holder for aluminum & plastic vehicles — reusable, paint-safe grip pad

Proper Design Gripper Mats™ let magnetic car signs adhere to aluminum, plastic and composite vehicle panels without glue or damage.

Modern cars, vans and trucks often have non-magnetic body panels, so traditional magnetic signs won’t stay put. Proper Design Gripper Mats are thin, reusable pads that sit between your existing magnetic sign and the vehicle surface to provide the traction magnets need to hold securely. They use a proprietary grippy surface developed to keep signs in place while protecting paint and allowing easy removal and repositioning.

How do Gripper Mats make magnets stick to non-magnetic panels?

Gripper Mats create a physical interface that prevents slippage between a magnetic sign and a smooth aluminum or plastic panel. The mat's engineered texture increases friction so the magnetic sign can hold as if attached to steel, without altering the vehicle.

• Place the mat on the panel, then position the magnetic sign over it.
• The mat’s grip material resists sliding and wind lift.
• No adhesives or permanent modifications required.

Will Gripper Mats damage my paint or leave sticky residue?

No adhesive, glue or harsh chemicals are used, so Gripper Mats are safe for painted surfaces when used as directed. The mats are designed to be removable and rinse-cleanable, helping preserve vehicle finish through repeated applications.

• Non-adhesive grip technology prevents residue buildup.
• Rinseable design for simple maintenance and reuse.
• Safe for clear coats and common OEM paints when applied correctly.

Can I use Gripper Mats with different types of magnetic signs and vehicles?

Yes—Gripper Mats work with most magnetic business signs, taxi top signs, car magnets and promotional panels regardless of size or magnet strength. They are suitable for aluminum bodywork, plastic panels, composite doors and other non-ferrous surfaces where magnets otherwise won’t attach.

• Compatible with large and small magnetic signs and plates.
• Effective on aluminum, plastic, fiberglass and composite panels.
• Reusable across multiple vehicles and applications.

How do I care for and position Gripper Mats for best performance?

Keep the mat and vehicle surface clean and dry for optimal holding power, and press the mat flat against the panel before applying your magnetic sign. When needed, remove the mat, rinse with water, let air dry, and reapply—no special cleaners required.

• Wipe the panel free of dirt, then place the mat firmly in position.
• Apply the magnetic sign over the mat, smoothing out edges to ensure contact.
• Rinse mats with water to remove grime; do not use solvents.

Who is this for? Proper Design Gripper Mats are intended for businesses, drivers and fleet operators who rely on magnetic signage but drive vehicles with aluminum, plastic or composite body panels. They are ideal for taxi services, delivery vehicles, mobile advertisers and tradespeople who need a non-permanent, paint-safe solution to display magnetic signs reliably across modern vehicle types.
