Assessing the Damage: Know Your Scratch

Before you begin any repairs, it’s crucial to assess the depth of the scratch. A simple way to determine this is the “fingernail test.” Run your fingernail across the scratch. If your nail catches on the scratch, it’s likely deep enough to require more than just a simple polish. Understanding the severity of the scratch helps determine the appropriate repair method.

Types of Scratches

Scratches are generally categorized into three types:

• Clear Coat Scratches: These are the most superficial, affecting only the clear coat layer.
• Base Coat Scratches: These penetrate the color layer, revealing the primer underneath.
• Primer Scratches: The deepest type, exposing the bare metal and increasing the risk of rust.

Knowing which type you’re dealing with will help you choose the correct repair strategy. For example, a clear coat scratch may just require polishing, whereas a base coat scratch may call for touch-up paint.
