The flagship Lexus LS will soon come with a special highly scratch-resistant clear coat which Toyota says possess self-restoring qualities. The clear coat is highly resistant to typical surface scratches usually caused by car wash brushes and fingernails. You can usually spot loads of fingernail scratches near your door handle area, and sometimes you’re bound to hit the paint while reaching to grab your door handle.
An ingredient in the new clearcoat apparently encorages molecular bonding, resulting in a denser structure than conventionally possible. This gives the coat flexibility and elasticity, making it less prone to damage and more resistant to light and acid, and giving it the ability to self-restore after deformation.
