Scratches on your car are frustrating — whether they come from a parking lot mishap, road debris, or accidental contact with a sharp object. While some scratches are minor and easy to fix at home, others require professional attention to restore your vehicle’s appearance and prevent long-term damage.
This guide walks you through how to repair a scratch on a car, from identifying scratch depth to choosing the right repair method. You’ll learn when DIY works, when it doesn’t, and how to protect your vehicle’s value through proper repair.
Step 1 — Identify the Type of Scratch
The Fingernail Test (Clearcoat vs Paint vs Primer)
Before you reach for any tools, you need to determine how deep the scratch is. The easiest method is the fingernail test: gently drag your nail across the scratch.
• If your nail does not catch, it’s likely a clearcoat scratch — the easiest kind to fix.
• If your nail catches slightly, the scratch has likely penetrated the paint layer.
• If you see gray or metal, the scratch has reached the primer or base metal — requiring more advanced repair.
Types of Scratches Explained
- Clearcoat scratches: Most common; occur from car washes or light brushes against objects.
• Base coat scratches: Deeper damage that removes color.
• Primer scratches: Reach the underlayer and may expose metal — high risk for rust.
Step 2 — Gather the Right Tools & Materials
For Light/Clearcoat Scratches
- Microfiber towels
• Scratch-removal compound
• Polishing pad or drill attachment
• Rubbing alcohol for cleaning
For Deeper Scratches
- Touch-up paint (exact paint code match)
• Clearcoat applicator
• Primer
• Sandpaper (1500–3000 grit)
• Masking tape for protecting edges
Typical Costs
- DIY scratch-removal kits: $15–$50
• Touch-up paint kits: $20–$60
• Advanced materials for deeper repairs: $50–$150
Step 3 — How to Repair Light (Clearcoat) Scratches
Clean the Area Thoroughly
Wash and dry the area to ensure no dirt or debris causes additional micro-scratches during repair.
Apply Scratch Remover Compound
Place a small amount of compound on a microfiber towel or pad.
Rub the compound over the scratch using firm, circular motions for 20–40 seconds.
Polish to Restore Shine
After wiping away excess product, polish the area to restore a smooth, glossy appearance.
Expected Results
Light scratches often fade significantly or disappear entirely with proper buffing.
Step 4 — How to Repair Deeper Scratches (Base Coat or Primer Damage)
Light Wet Sanding
Use 1500–2000 grit sandpaper to gently level the edges of the scratch. Do not oversand — this step requires care.
Apply Touch-Up Paint
Use your vehicle’s paint code to match color.
Apply thin, even strokes, allowing each layer to dry.
Seal With Clearcoat
After the paint dries, apply a clearcoat layer to protect the finish and blend with surrounding paint.
Final Polish
Once fully cured, polish the area for a consistent shine.
When DIY May Not Be Enough
- The scratch is large or jagged
• The color match is imperfect
• The scratch lies on a curved body line
• The damage appears from a collision or keying
In these cases, DIY often results in uneven texture or mismatched paint.
Step 5 — When You Should Not DIY a Scratch Repair
Deep Scratches Exposing Metal
Unprotected metal begins rusting quickly, especially in wetter climates.
Multiple or Long Scratches
Attempting large DIY touch-ups often creates patchy or inconsistent results.
Scratches Near Sensors or Cameras
Modern cars have ADAS systems near bumpers, mirrors, and quarter panels. DIY repair may interfere with sensor calibration.
Damage From a Collision
This usually requires sanding, repainting, and refinishing — best handled professionally.
Many drivers rely on Relux Collision Sacramento for deep scratch repair, collision refinishing, and expert color matching using professional-grade equipment and processes.
Step 6 — Additional Professional Repair Options
Paint Correction / Machine Polishing
Ideal for deeper clearcoat scratches or swirl marks. Professionals use multi-stage polishers to restore gloss safely.
Professional Touch-Up & Blending
Blending ensures the repaired area transitions seamlessly — something DIY struggle with.
Full Panel Repainting
Used when the scratch is severe or spans a large area. This ensures long-term durability and perfect paint match.
For the best long-term results, many car owners turn to Relux Collision for high-quality refinishing, full-panel repainting, advanced paint-matching technology, and precision auto body restoration.

How to Prevent Future Scratches
Proper Washing Techniques
Avoid automatic car washes with brushes; they cause micro-scratches.
Use Paint Protection Film or Ceramic Coating
Adds a protective barrier against scratches and UV exposure.
Park Strategically
Avoid tight spots, shopping cart areas, and overgrown bushes.
Conclusion
Repairing a scratch on a car starts with understanding the depth and severity of the damage. Light clearcoat scratches can often be fixed at home, but deeper scratches require expertise to ensure a flawless finish and long-term protection.
Whether you choose DIY or professional repair, taking action early prevents further damage and protects your vehicle’s appearance and value.
