Mobile Advertising in Memorable Shapes

Custom-shaped car magnets offer the flexibility of removable vehicle advertising with a format that can reflect your industry or promotional message.

House and apartment shapes are well suited to real estate, property management, construction, roofing, and home-service businesses. Arrows can emphasize a phone number, offer, or call to action. Stars can support special promotions, recognition campaigns, entertainment branding, and event advertising. Circles and octagons provide balanced formats for logos, badges, seals, and high-impact graphics.

Because these signs are removable, they are useful for businesses that share vehicles, run seasonal campaigns, or need temporary branding without installing permanent adhesive graphics.

30 Mil White Vinyl Magnetic Material

Custom-shaped car magnets are produced from 30 mil (0.76 mm) white vinyl magnetic material. The white face provides a bright printing surface for full-color graphics, while the magnetic backing attaches to compatible ferromagnetic metal.

The material is intended for indoor and outdoor applications and can perform in typical rain, sleet, snow, and temperature changes when installed and maintained correctly.

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

Professional Matte Finish

The matte surface helps reduce glare from sunlight and artificial lighting. This can make logos, phone numbers, websites, and service information easier to see from different angles.

For effective vehicle advertising:

• Use large, bold lettering.

• Maintain strong contrast between text and background.

• Keep the message concise.

• Prioritize the business name, main service, and contact method.

• Avoid positioning text in narrow points or shaped corners.

• Use high-resolution logos and graphics.

• Make QR codes large enough to scan reliably.

Full-Color Front Printing

Custom-shaped car magnets are printed in full color on the front, with no printing on the magnetic back. Customize your design with:

• Business name and logo

• Phone number

• Website and email address

• Social media information

• QR code

• Products or services

• Service area

• License or certification information

• Promotional offer

• Event or campaign message

• Custom photographs or illustrations

Keep all essential information safely inside the shape’s trim area. The available safe area can be smaller than the overall dimensions, particularly around arrow points, star points, rooflines, and other shaped edges.

Ideal Uses and Applications

• Real estate agents

• Apartment communities

• Property-management companies

• Home builders and remodelers

• Roofing and landscaping businesses

Vehicle and Surface Compatibility

Before installation, 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, grease, wax buildup, dirt, and debris

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

• In sound condition with fully cured paint

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

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

Proper Installation

Follow these steps before driving with a custom-shaped car magnet:

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 contact the panel gradually.

5. Smooth the magnet outward to remove trapped air.

6. Confirm that the entire backing contacts the vehicle.

7. Inspect every point, corner, curve, and shaped edge.

8. Recheck the magnet after weather exposure, cleaning, or repositioning.

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

Cleaning and Maintenance

Remove the magnet regularly to clean and dry both the magnetic backing and vehicle surface. Dirt and moisture trapped underneath can reduce magnetic contact and may affect the finish.

Recommended care:

• Clean with mild soap and water.

• Avoid abrasive tools and harsh chemicals.

• Dry both surfaces completely before reapplication.

• Reposition the magnet periodically.

• Remove it before automatic car washes.

• Inspect all points and shaped edges before every trip.

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

Specialty shapes may contain narrow sections or points that require additional inspection to ensure complete surface contact.

Storage Instructions

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

Weather and Temperature Performance

The material is designed 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 may be affected by:

• High driving speeds

• Strong winds

• Severe weather

• Extreme temperatures

• Curved or uneven panels

• Dirt or moisture beneath the magnet

• Road debris

• Incomplete surface contact

• Improper storage

• Lifted points or shaped edges

Remove the magnet whenever 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 when the material, printing, edges, or magnetic hold begins to deteriorate.
