Abstract
A hard, transparent coating for a substrate and associated method for coating is disclosed. The coating includes alternating layers of a soft coating and a hard coating. The coating further includes a sensor. The electrical resistivity of the sensor may be measured to determine if the coating has been degraded. The coating may further include a hydrophobic outer layer.
