Your car already goes all over town. Why not let it advertise for you? Car magnet signs stick to your doors in seconds and come off just as fast, so you can use your work vehicle as an ad during the week and a personal car on the weekend. At Galvan Media, we print custom car magnets for businesses in Corona, CA.

Why Choose Car Magnet Signs?

  • Low cost: Much cheaper than a full vehicle wrap.
  • Removable: Take them off for personal trips or when you sell the car.
  • Reusable: Move them to a new vehicle anytime.
  • Always on: Your ad works while you drive and while you are parked.

They are a smart choice for realtors, contractors, cleaners, delivery drivers, mobile mechanics and anyone who uses a personal car for work.

Popular Sizes

Most car doors fit a magnet around 12 x 18 or 12 x 24 inches. Trucks and vans can handle larger sizes, such as 18 x 24 inches or more. We can also make custom shapes and small magnets for the back of your vehicle. Measure the flat area of your door first, and avoid curves, trim and body lines. See all options on our magnets page.

Design Tips for Car Magnets

  1. Keep it short. Drivers see your car for just a few seconds. Name, service and phone number are enough.
  2. Make the phone number big. It is the most important detail.
  3. Use bold contrast. Dark text on white, or white text on a dark color.
  4. Show your logo. It builds recognition every time people see you around town.
  5. Add your website or QR code. QR codes work best when people are close, like in a parking lot.

How to Care for Car Magnets

  • Apply only to clean, dry, flat steel surfaces. Magnets will not stick to aluminum or fiberglass panels.
  • Remove and clean the magnet and the car surface once a week to prevent moisture buildup.
  • Take magnets off before going through a car wash.
  • Store them flat, never folded or rolled tightly.
  • Check that edges sit flat before driving on the freeway.

Car Magnets vs. Vehicle Wraps

Magnets are perfect for a low-cost start or for personal vehicles. A full or partial wrap gives you more space and a bolder, permanent look. Many businesses start with magnets and move to a wrap as they grow. Read our guide to vehicle wraps or see our decals and wraps page.
