om, liberally apply water to the vehicle body, wheel

caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.

The restoration time may become shorter when the coating is warmed by applying
warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle.
