Car Magnets

• Remove Existing Decals, For proper function, custom vehicle magnets need direct contact with the truck door's metal surface. Installing over existing car door signage creates barriers that prevent secure adhesion and form air pockets. This separation compromises performance and risks permanent damage to both the magnetic material and existing car decals.

• Clean Area Thoroughly and Inspect Condition, Cleaning the car surface ensures you carefully examine for existing paint damage, scratches, or rusting, which make areas unsuitable for magnetic signs. Use mild detergent to reveal the true condition of your vehicle surface and prepare it for your mobile billboard application.

• Verify Metal Surface, Check if your car door is steel, aluminum, or fiberglass. Only steel surfaces work with vehicle magnets. Modern trucks and luxury vehicles often use aluminum body panels requiring our reusable car decals instead.

• Consider Frequency, Ask yourself: "How often will I remove this custom car magnet?" Magnetic car signs require weekly maintenance, especially after car wash sessions or high speed driving in the rain. For minimal upkeep, choose our permanent car signs such as truck decals or vehicle lettering instead.

Carefully measure the flat car surface where you plan to install your magnetic car signs. Proper sizing is the #1 factor for long-lasting magnet performance - wrong size is the leading cause of magnets flying away. 

• Accurate Measurement is Essential: Use a proper tape measure for precise dimensions. Take the time to do it right. Record exact measurements to ensure professional results and optimal magnet performance.
• Measurement Guidelines: Only measure completely flat areas on the car door or vehicle surface. Your custom vehicle magnets must sit entirely flat against the metal surface with no air pockets. Avoid door handles, jams, emblems, moldings, and recessed areas that create separation.
• Full Contact is Critical: Even small overhangs onto trim areas will cause failure.  Custom vehicle magnets require complete contact with the flat surface.  A common misunderstanding is that partial overlap is acceptable since most of the magnetic material contacts the flat surface. However, any air gap creates instability. Air infiltration through gaps leads to detachment and potential loss to your car door signage.

Once you’ve gathered all your measurements and your logo,  log on to Signazon and start your custom car magnet order.

• Size: You can choose from a wide variety of standard sizes or enter custom dimensions to perfectly match your needs. Our custom sizing ensures a flawless fit, especially crucial for car magnet signs.
• Shape:  Oval or round shapes to make your truck magnets stand out.

Consider these tips for an impactful car magnet for business advertising design:

• Headline: Promote your business, product, or service. Include your company’s tagline.
• Readability: Use contrasting colors, like a white background with dark blue or black text. Font Size: Ensure readability from a distance. As a guide, 1 inch of text is visible from 10 feet away—scale accordingly. so if you want someone to see it 30 feet away your text should be at least 3 inches tall, 40 feet should be 4 inches, and so on.
• Simplicity: Keep the message clear. Focus on your core services, logo, website, and a prominent phone number.

Your custom car magnets from Signazon undergo rigorous quality assurance and comprehensive strength testing to ensure high quality adhesion to metal surfaces. To maintain this performance standard, indoor temperature and keeping it flattening are 2 key factors.

• Store Indoor 50-100 Degrees: Immediately bring custom vehicle magnets indoors upon arrival. Extreme hot and cold temperatures cause demagnetization & permanent damage to ferromagnets type magnetic material. Temperature fluctuations cause expansion and contraction, potentially creating stress points in the magnet-paint interface on the metal surface. Never leave magnetic signs rolled up in shipping boxes outside or in garage. Always store magnets flat indoors. 

• 24-Hour Flatten Rule: Place car door magnets on refrigerator door for 24 hours minimum. This flattens and re-magnetizes magnetic car signs after shipping, ensuring optimal adhesion performance.

• Installation Process: Clean the area on your vehicle where you want to install the sign with soap and water, then dry it completely. Carefully attach the magnet to the flat steel surface and remove any air pockets.

To prevent prolonged contact creating permanent bonding between magnetic material and your vehicle surface, magnetic car signs require regular maintenance intervals.

• Car Wash: Always remove magnetic signs before car wash sessions to prevent water damage and chemical entrapment. Wait until vehicle is completely dry before reapplication.

• Post-Waxing: After waxing and polishing your vehicle, allow at least two days for complete curing before reapplying personalized car magnets.

• Weekly Rest Period: Remove car door magnets weekly to prevent moisture and dirt buildup. Allow 24-hour window without magnets prevents chemical reactions and permanent damage to your car surface while allowing even exposure on the vehicle surface.

• Cleaning Best Practices: Clean both the custom car magnet back side and metal surface weekly using mild detergent. Wipe with soft cloth or air-dry completely. Dirt accumulation creates abrasive conditions during removal that can damage your vehicle surface.
