Like all magnets, our car magnets stick to ferromagnetic metals, including iron, steel, nickel and cobalt. They will not stick to aluminum, fiberglass, wood or plastic. You can test what part of your car is magnet-compatible by sticking a refrigerator magnet on it. If the refrigerator magnet doesn’t stick, try our car door decals – which are made with a long-lasting adhesive.

Each car door sign is made of 0.85 mm thick PVC-free vinyl with a magnetic strength of 90 lbs. per square foot.

With proper care and use, custom car magnets can be used for about 2 years. At that point, we recommend replacing your magnet to prevent it from falling off your vehicle when you drive. See FAQs below for more maintenance tips.

We recommend creating an advertising magnet in a different (yet complementary) color. This helps your magnet stand out and is the easiest way to create a consistent look across multiple vehicles of differing colors. Just make sure you keep your messaging and design simple and clear.

No, you’ll want to wait for your paint (or clear coat/wax job) to cure. The recommended wait time is 90 days for a new coat of paint, 60 days for a clear coat and 7 days for a wax.

With proper application, your magnet should stay in place for up to two years. We recommend the following application method:

1. Clean: Clean the vehicle surface and magnetic back with a damp cloth and mild detergent.
__2. Dry: __Let both your vehicle surface and your car magnet air dry completely.
3. Apply: Apply the magnet to a flat, metallic surface without bumps, curves or rust.
4. Maintain: To avoid damage to your vehicle, we recommend removing and reapplying your car magnet every 2-3 days. Clean the back of your car sign and vehicle surface weekly with a damp cloth and mild detergent.

You’ll know the magnet is properly installed if it adheres to the surface, if there are no air bubbles between the magnet and the vehicle surface, and if the magnet (including the corners) is flat against the surface.

We recommend removing and reapplying your magnet every 2-3 days. Leaving the sign on for long periods may cause damage to your vehicle’s paint. Clean the back of your car sign and vehicle surface weekly with a damp cloth and mild detergent. This will protect your vehicle and magnet against debris and build up.

Following these tips will extend the life of your magnet and protect the surface to which it’s applied. Failure to do so can result in permanent damage to the vehicle and magnet.

1. Remove your magnet before any professional car washes or power washing

2. Do not use your vehicle magnet in extreme weather conditions

3. Remove and reapply your car magnet every 2-3 days

Note: Applying any material to a painted surface without following these application, care and usage instructions may result in damage to the surface. (See our terms and conditions for more information.)

We recommend not using the magnet during extreme weather conditions (temperatures exceeding 160° F or below -15° F).

Yes. We recommend removing it before any professional car washes or power washing to avoid damage to the vehicle surface.

Our PVC-free material option is made of durable, weather-resistant polyester. While this polyester is just as durable (designed for up to 2 years of use), it does not include the traditional plastic used in vinyl banners.

To ensure the best quality for custom-shaped products, please follow these design guidelines:

1. Avoid small, floating elements
2. Avoid very fine lines and detail
3. Keep edges smooth and simple
4. Upload high-resolution artwork
5. Keep important text or parts of your design away from the safety lines laid out in the design tool
