Important Magnet Information

Magnetic signs only stick to flat steel surfaces. They will not adhere to aluminum, fiberglass, plastic, carbon fiber, heavily curved panels, or areas with body filler. Before ordering, measure your flat door space and test with a household magnet if unsure.

For best performance and longevity, remove and clean your magnetic sign regularly. Clean both the vehicle surface and the back of the magnet after rain, road salt, dirt, or car washes to protect your vehicle finish and extend magnet life.
