1. Understanding the Severity of Car Scratches

What are the different types of car scratches and how do you assess the damage?

Understanding the type and severity of a car scratch is crucial for choosing the right repair method. Scratches typically fall into three categories: clear coat scratches, paint scratches, and deep scratches that reach the metal. Assessing the damage involves a close inspection to determine the depth and extent of the scratch.

• Clear Coat Scratches: These are the most superficial, affecting only the clear coat layer. They often appear as minor blemishes and can usually be fixed with simple polishing.
• Paint Scratches: These scratches penetrate the clear coat and affect the paint layer. They are more noticeable and require more extensive repair, such as touch-up paint.
• Deep Scratches: These are the most severe, reaching the metal layer beneath the paint. They require thorough repair to prevent rust and maintain the structural integrity of the vehicle.

According to a study by the University of Michigan Transportation Research Institute, the average cost of repairing a deep scratch can range from $500 to $1500, depending on the size and location of the scratch. Knowing the severity helps you estimate repair costs and choose the appropriate tools and materials from CARDIAGTECH.NET.
