1. Understanding Car Scratches

Before diving into the process of buffing scratches, it’s important to understand the different types of scratches that can occur on a car’s paint.

1.1. Types of Car Scratches

Understanding the type of scratch is crucial for choosing the right buffing method. Here’s a breakdown:

Scratch Type	Description	Severity	Solution
Clear Coat	Minor scratches that only affect the clear coat layer.	Light	Polishing compound and buffing.
Base Coat	Scratches that penetrate the clear coat and reach the base coat (color layer).	Moderate	Requires more aggressive buffing or touch-up paint.
Primer	Scratches that go through the clear coat and base coat, reaching the primer layer.	Severe	Sanding, filling, and repainting may be necessary.
Metal/Bare Body	Scratches that go through all layers of paint, exposing the metal body.	Very Severe	Requires professional repair to prevent rust and structural damage.
Spiderweb Swirls	Circular, hairline scratches often caused by improper washing or polishing techniques.	Light	Gentle polishing and proper washing techniques.
Transfer Scratches	Marks left by another vehicle’s paint or material.	Light	Can often be removed with a clay bar and polishing compound.

1.2. Assessing the Damage

• Visual Inspection: Examine the scratch under good lighting. Use your fingernail to gently feel the scratch. If your nail catches, the scratch is likely deep enough to require more than just buffing.
• The Water Test: Pour water over the scratch. If the scratch disappears when wet but reappears when dry, it’s likely only in the clear coat and can be buffed out. If the scratch is still visible when wet, it’s deeper and may require additional repair steps.
