What Are Custom Car Magnets?
They are great for businesses that want to announce temporary sales and seasonal specials, political campaigns, and more. The product is cost-effective, weather-tested, and fully customizable. Magnetic car signs help your business achieve maximum visibility and reach wider audiences.
Business car magnets are easy to use. They require no effort on your part other than sticking the sign to the vehicle. Their main advantage is their reusability. They don’t damage your car paint and are super easy to apply and remove. You can even use custom business vehicle magnets on rented cars or remove the graphics after working hours and use the car for personal needs.
Please keep in mind that magnets aren’t compatible with all materials, and not even all metals. They mainly work with steel. Make sure that this product is the right choice for your vehicle before placing an order.

- Rounded: With this cutting option, the sign edges will be rounded at a ¼”–½” radius. Good for vehicles thanks to its aerodynamic properties, and the soft corners resist peeling and lifting at highway speeds.
- Circle/Oval Cut: Oval or round car magnets create a natural focal point. Good for logo-centered designs, as the shape draws the eye straight to your brand.
- Custom Cut: Get your car or truck magnets outline-cut with elaborate forms by selecting the option in our tool. Good for standing out in traffic, since a unique silhouette makes your magnet instantly recognizable.
- Custom Cut with Border: Add a matte white border of ¼”–½” around your design, cut into your desired shape. Good for improving readability, as the border makes your artwork pop against any vehicle color. Keep in mind that the border is included in the size you choose for your magnet.

How to Install Custom Car Magnets
- Step 1: Make sure the area you are placing your magnet on is clean and smooth.
- Step 2: Double-check that it is metal by testing it with a refrigerator magnet first.
- Step 3: Place the magnet on the surface. Start with one edge of the magnet and smooth it flat across to the other side.
Avoid placing the magnet near your gas tank. You should also never drag or slide the magnet. If you want to reposition it, completely remove it from the car’s surface first.
How to Prevent Vehicle Magnetic Signs from Falling Off
Choose a completely flat surface and clean it as described above to avoid moisture, dust, or air bubbles from getting trapped underneath the product.
We don’t recommend using this non-adhesive medium on the hood, roof, or other horizontal surfaces of the vehicle. These areas have higher exposure to wind, which increases the possibility of the product coming off.
How to Take Care of Custom Car Magnets
- Make sure both the product and application surfaces are clean and dust-free before every application.
- Wash the back of the product with mild detergent and warm water. Make sure both surfaces are completely dry before application.
- Clean and reapply your vehicle magnets every time after rain and snowfall or in case of humid weather conditions. This will prevent moisture from getting stored between the graphics and your car’s body.
- Always remove the graphics before entering a car wash. Although business advertising car magnets are waterproof, the chemicals used during washing may damage the printed graphics.
Store the product completely flat. If you do need to roll it, the printed surface should face outward to avoid wrinkles.
Alternative Signage for Non-Magnetic Vehicles
Aluminum won't hold a magnet, though, so drivers with these vehicles need a different way to display their branding or message.
Custom car decals are an alternative and are backed with a strong adhesive that bonds directly to any smooth surface on your vehicle. Each option has its strengths, so the right choice depends on how you plan to use it:
| Car Magnets | Car Decals | |
|---|---|---|
| Compatibility with non-magnetic surfaces | No | Yes |
| Removable and reusable | Yes, take it off and reapply anytime | No, single-use once applied |
| Highway speeds | May lift or fly off at high speeds | Stays in place |
| Curved or contoured panels | Needs a flat surface for full contact | Conforms easily to curves |
| Best for | Temporary or rotating signage | Long-term, set-it-and-forget-it branding |

This product is tested to stay put at speeds up to 80 mph (128.74 kph) under normal weather conditions. Keep in mind that this doesn’t take into account high winds blowing in the opposite direction of your driving. Avoid placing the product on horizontal car surfaces like the hood and roof to minimize wind resistance.
Yes, we can cut your vehicle magnet in practically any shape you like.

Custom car magnets last 3–5 years if you take proper care of them.
Make sure both the application surface and the product are clean and dust-free. Choose the flattest area since the magnet won’t stick well to curved surfaces. Place the product onto the area of application and check if the whole surface has securely adhered to the vehicle body. Change the position if any edges stick out to prevent the risk of your magnet being blown off by wind resistance.
Make sure to remove the sign and clean it along with the application area once or twice a week. Remove and dry both surfaces after rain and snowfall. Don’t slide the car magnet when removing it to prevent any dust stored underneath from scratching the surface of your car.
Place the magnet on a smooth surface and cover it with a soft cloth. Don’t roll or fold it in order to avoid wrinkles on the printed side. If you must roll the graphics for transportation or storage, make sure you do so gently and evenly with the printed side facing outwards.
