While ceramic coatings are designed to be highly durable and resistant to scratches, they are not completely scratch-proof. Ceramic coatings can still get scratched if they come into contact with abrasive materials, such as sand or gravel, or if they are not properly cared for.
The level of scratch resistance will also depend on the type and quality of the ceramic coating, as well as the thickness of the coating layer applied. High-quality ceramic coatings that are properly applied and maintained can provide excellent scratch resistance, but they will not completely eliminate the risk of scratches.
If a scratch does occur on a ceramic coated surface, it may only affect the coating and not the underlying paint. However, if the scratch is deep enough, it may penetrate through the coating and damage the underlying paint.
It's important to note that while ceramic coatings can provide excellent protection against scratches, they are not a substitute for proper car care and maintenance. Regular washing, detailing, and careful driving can help to minimize the risk of scratches and keep your car's finish looking great for longer.
