Turn Your Vehicle into a Mobile Billboard

Custom car magnets help your business gain visibility during service calls, deliveries, daily travel, and parked displays. Add your company name, logo, phone number, website, service area, or call to action to create a professional sign that promotes your organization wherever the vehicle goes.

Unlike permanent decals, magnetic vehicle signs can be removed when the vehicle is used for personal travel or when a campaign ends. They are a practical choice for contractors, real estate professionals, delivery services, cleaning companies, landscapers, mobile service providers, and organizations that need flexible vehicle identification.

30 Mil White Vinyl Magnetic Material

Car magnets are made from 30 mil (0.76 mm) white vinyl magnetic material. The white printable face provides a bright foundation for full-color graphics, while the magnetic backing attaches to compatible ferromagnetic metal surfaces.

The material is designed to resist typical outdoor conditions such as rain, sleet, snow, and temperature changes when the magnet is installed, cleaned, and maintained correctly.

Not every vehicle panel is magnetic. Aluminum, fiberglass, plastic, carbon fiber, glass, body filler, and some stainless steel surfaces will not hold a magnet. Always test the exact placement area before ordering or installation.

Professional Matte Finish

The matte surface helps reduce glare from sunlight and artificial lighting, allowing essential information to remain easier to see from different angles.

For effective vehicle advertising:

• Use large, bold lettering.

• Maintain strong contrast between the text and background.

• Keep the message short and easy to understand.

• Prioritize your business name, primary service, and contact method.

• Avoid overcrowding the design.

• Use high-resolution logos and images.

Keep essential information safely inside the trim area and ensure it can be read quickly from a practical viewing distance.

Compatible Surfaces

Custom car magnets are intended for flat, smooth, compatible magnetic metal surfaces, including certain:

• Vehicle doors

• Vehicle body panels

• Steel filing cabinets

• Metal storage units

• Magnetic display boards

• Equipment cabinets

• Indoor metal displays

A surface that looks metallic may not contain enough iron to hold a magnet. Test the intended area with a separate magnet before installation.

Vehicle Compatibility Checklist

Before applying your car magnet, confirm that the placement area is:

• Magnetic and capable of holding the sign securely

• Smooth and substantially flat

• Clean and completely dry

• Free from rust, wax buildup, grease, dirt, and debris

• Free from deep curves, molding, trim, creases, and panel gaps

• In sound condition with fully cured paint

Use caution with recently painted, repainted, repaired, wrapped, damaged, or nonfactory vehicle finishes. Consult the vehicle, paint, or wrap manufacturer when compatibility is uncertain.

Do not place magnets over windows, lights, license plates, cameras, sensors, vents, safety markings, door seams, or areas where the sign could interfere with vehicle operation or legal visibility requirements.

Proper Installation

For secure attachment and responsible use:

1. Wash and dry the vehicle panel and magnetic backing.

2. Confirm that the surface is smooth, flat, and magnet-compatible.

3. Make sure the magnet is clean, dry, flexible, and completely flat.

4. Position one edge first and allow the remaining surface to make contact gradually.

5. Smooth the magnet outward to remove trapped air.

6. Confirm that the entire backing and every edge sit flush against the vehicle.

7. Inspect the magnet before driving and after severe weather, cleaning, or repositioning.

Do not drive with a folded, curled, damaged, wet, dirty, or partially attached magnet.

Cleaning and Maintenance

Regular maintenance helps support magnetic hold and protect the vehicle surface.

• Remove and inspect the magnet frequently.

• Clean the magnet and vehicle panel with mild soap and water.

• Avoid abrasive tools, harsh chemicals, and petroleum-based cleaners.

• Dry both surfaces completely before reapplying the magnet.

• Reposition the magnet periodically.

• Remove it before automatic car washes.

• Inspect all edges before every trip.

• Store the magnet clean, dry, and flat when it is not in use.

Dirt, moisture, road salt, and other contaminants trapped beneath the magnet can reduce attachment strength and may affect the vehicle finish.

Storage Instructions

Store the car magnet flat whenever possible. Do not fold, crease, or place heavy objects unevenly on top of it.

If temporary rolling is necessary, roll it loosely with the printed side facing outward. Allow the magnet to return to a completely flat condition before applying it to a vehicle.

Weather and Temperature Performance

The magnetic material is intended to perform in temperatures ranging from approximately −15°F to 160°F (−26°C to 71°C). It can withstand ordinary exposure to rain, sleet, and snow when properly installed and maintained.

Performance can be affected by:

• High driving speeds

• Strong winds

• Extreme temperatures

• Severe weather

• Curved or uneven panels

• Road debris

• Dirt or moisture beneath the magnet

• Incomplete surface contact

• Improper storage

Remove the magnet when secure attachment is uncertain.

Estimated Outdoor Lifespan

The estimated outdoor lifespan is approximately 3–6 months. Actual longevity depends on sunlight, weather, driving frequency, installation, cleaning, storage, surface compatibility, and exposure to dirt, salt, chemicals, or road debris.

The stated lifespan is an estimate rather than a guarantee. Inspect the magnet regularly and replace it if the material, printing, edges, or magnetic hold begins to deteriorate.

• Contractors and construction companies
