Wonder Wheels Wheel Sealant is a revolutionary instant wheel sealant that leaves an invisible, protective shield over the wheel surface. This creates a barrier against the build-up of stubborn brake dust, road grime, and dirt. The sealant produces a super repellent nano film which self-cleans when rained on or rinsed with water. It is easy to apply and suitable for all wheel types, including alloy wheels. The sealant protects the surface of the wheels, keeping them cleaner for longer. For best results, wheels must be clean and dry before application. Shake the can well and spray a light coating over the exposed areas of the wheels, treating one wheel at a time. Allow to dry for at least one hour. For outdoor use only. This product produces a semi-permanent coating. If the vehicle is washed and the wheels are cleaned with agitation, re-apply the sealant.
