The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused by a car wash, etc.

●

The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.

●

The restoration time differs depending on the depth of the scratch and outside
temperature.
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.
