Designed for use after the application of Universal Wheel Cleaner. The Wonder Wheels Wheel Sealant leaves an invisible, protective shield over the wheel surface, creating a barrier against the build-up of stubborn brake dust, road grime and dirt. Once applied, Wonder Wheels Wheel sealant produces a super repellent nano film, which when rained on or rinsed with water, self-cleans. Simply spray on using the easy to use aerosol and allow to dry. Apply to instantly shield your wheels leaving a Smooth, glossy finish.
