Yes—our custom magnets are strong enough to adhere securely to cars and stay put at highway speeds, thanks to a pull strength of 317.36 kgf/m².
When used correctly, flexible magnets generally won't damage car paint. Most issues happen when dirt, moisture, or heat get trapped underneath the magnet, so we recommend the best practices below.
Best practices for car use
- Apply to a clean, flat metal surface (avoid dents, deep curves, or heavily contoured panels).
- Remove and reposition regularly—weekly is ideal.
- Each time you remove it, wipe away trapped dirt/debris and dry any moisture underneath before reapplying.
- Store flat when not in use to prevent warping.
- Don’t apply over decals or vinyl wraps.
- Avoid prolonged extreme heat (like direct sun for long periods), which can compromise the magnet backing.
