What are car magnets? 

Car magnets serve as your business card on the road. These auto signs are printed on a 30 pt. magnetic stock that sticks firmly and seamlessly to any vehicle, giving it a custom-painted look.  

Durable and UV-resistant, custom car magnets are an economical way of promoting any business. Order them once and use them for many years. Update your messaging as frequently as you need or remove the signs when your vehicle is “off duty”. 

Boost Attention to Your Message With Custom Car Magnets

Car magnets come in a variety of shapes and sizes, allowing you to drive more attention to your message or branding. Choose from the following traditional shapes: 

  • Rectangle/Square 
  • Oval  
  • Circle 

 

Magnetic car signs are also available in custom shapes and sizes to make your message stand out even more. To personalize your car magnets, choose Custom Size and Custom Shape from the dropdown menu.

How to Install Car Magnets

Installing car magnets takes only a couple of minutes. Before using them, find the best spot where customers will see your advertisements. Car magnets are usually installed in two places: 

  • Side of the vehicle – Side placement makes it easy for customers to see your magnetic sign while your vehicle is parked on the street. 
  • Back of the vehicle – If your vehicle is on the move, back placement lets the drivers behind you to see your message.  

 

Now it’s time to put the magnets in place. Here’s how to do it: 

  1. Before installing, place the magnet on a flat magnetic surface for at least 24 hours to flatten it.
  2. Wipe the vehicle surface and back of the magnet with a wet cloth and detergent. Let dry.  
  3. Place one end of the magnet in the desired position. Line up the other edge of the magnet, making sure that it’s flat against the metal surface.  

Note: Make sure that the vehicle surface is flat and entirely metal where the magnet will be placed. Avoid installing on surfaces where there are protrusions (molding, decals, pinstripes, etc) because these will prevent the magnet from sticking securely to your vehicle.

Extend the Life of Car Magnets

Magnetic car signs are durable, but with proper care, you can use these signs for as long as two (2) years.  

When cleaning your vehicle, remove the magnet to clean debris from the vehicle surface. This will help extend the magnetic hold of the magnet and prevent any damage to the car sign.  

If you will not be using the car magnets for a long period, store them flat and away from direct sunlight.

Car Magnets FAQs

Magnets do not cause any paint damage when installed carefully. However, they do not always adhere well to fresh paint. To avoid scratches on your newly painted vehicle and ensure that the magnet stays on, we recommend waiting for the paint to cure or harden for 90 days.  

Car magnets stick on most metals. When installing magnetic car signs, take note of its placement. Most car doors are made of steel, which is well-suited to magnets. However, some car doors contain only a small amount of steel and are not suitable for car magnets. Before placing an order, test if your car door is magnetic by attaching a small magnet to it.  But if you are going to mount it elsewhere on the vehicle, the magnet may not stick properly. Carbon fiber, plastic, and brass are not ideal for magnet placements.

Yes, car magnets are repositionable, so you can remove and stick them to the same or another vehicle. Just make sure to follow the proper way of cleaning and installing them.

Yes, you can get car magnets as large as 48” x 36”. Choose Custom Size on the dropdown menu and input your dimensions.

Although car magnets are durable, the print on car magnets can fade faster when exposed to direct sunlight. It is not recommended to place your magnets on hot metal surfaces like the hood of your vehicle. Extremely cold weather can also make the magnets brittle. Make sure that the magnet is at room temperature when applying it on your vehicle.  

Yes, the matte coating offers good writability. We suggest using a Sharpie and letting the ink dry a couple of minutes before handling to avoid smearing. 

Apply magnets to flat, smooth metal surfaces only. Avoid curved, plastic, or aluminum areas and always clean the surface before application.

Yes. Larger or thicker car magnets usually hold better than smaller or thinner ones. A clean, flat metal surface also helps improve adhesion.

Use large, bold text and high-contrast colors so your car magnet is readable from a distance. For best results, keep main text about 1 inch tall or larger and review your design at full size.

22”x22” Car Magnet beats Car Wrap

“The picture quality is very detailed that looks like it was retouched compared to the design that I sent. I couldn’t believe it. It was phenomenal. My first order was about 10”x18”. This time it’s 22”x22” at the custom size. It fits exactly on my 2015 Prius second row door. I was initially planning to get a side-doors car wrap but it would be $1,500-$2,000. This 22”x22” is big enough to get attention for $130(two pieces) including tax and shipping. Great value!”
Very Nice...
