Use and Care Instructions

Remove magnets about once a month to clean the surface to prevent any potential build up.

Do not apply magnets to your vehicle if your vehicle recently underwent a paint or waxing job. Check for the proper cure time of the coating before applying magnets.

Make sure to apply magnets to a clean surface. Any particulates under the magnet may rub and cause damage over time.
