Keying a car is a frustrating and costly experience. It’s a deliberate act of vandalism that can leave deep scratches in your car’s paint, ruining its appearance and lowering its value. Fortunately, you can often repair keyed car scratches yourself, saving you the cost of professional repair. This guide will walk you through the process step-by-step, explaining the different methods and materials you’ll need.

Assessing the Damage and Choosing Your Repair Method

The first step is to assess the damage. Keyed scratches vary in severity, and the repair method will depend on the depth and severity of the scratch.

• Shallow scratches: These scratches only affect the clear coat layer of the paint. You may be able to fix these with a simple touch-up pen or polish.
• Deep scratches: These scratches reach the base coat or even the primer layer, exposing the bare metal. You’ll need a more complex repair involving filling the scratch with putty, sanding, and repainting.

How to Determine if a Scratch is Shallow or Deep

You can use your fingernail to test the depth of the scratch. If your fingernail catches on the scratch, it’s likely a deep scratch. If your fingernail slides over it smoothly, it’s probably a shallow scratch.

• Let it dry: Allow the paint to dry completely before moving on to the next step.
