Step-by-Step DIY Scratch Repair Guide
Step 1: Clean the Area Thoroughly
Use car shampoo and water to clean the scratched area. Dry it completely with a microfiber cloth. Dirt or debris can interfere with the repair and cause more damage if not removed.
Tip: Never attempt scratch repair on a dirty surface—it can lead to worse scratches.
Step 2: Assess the Depth of the Scratch
Run your fingernail gently across the scratch:
-
If your nail doesn’t catch, it’s likely a clear coat scratch.
-
If it catches slightly, you’re probably dealing with a base coat scratch.
-
If it catches deeply and you see a different color or metal, it’s a deep scratch.
Step 3: Sand Lightly (For Deeper Scratches)
Use 1500–2000 grit wet/dry sandpaper soaked in water to gently smooth the edges of the scratch. This helps the repair blend more naturally into the surrounding paint.
Caution: Don’t over-sand—especially if the scratch is only in the clear coat. You risk removing too much paint.
Step 4: Apply Scratch Repair Compound or Rubbing Compound
For light scratches, apply a scratch remover compound or rubbing compound using a microfiber cloth. Use a circular motion and apply gentle pressure. This will help buff out the clear coat scratch.
Wipe clean with a dry cloth to assess progress. Repeat if needed.
Step 5: Use Touch-Up Paint (If Base Coat Is Exposed)
For deeper scratches, you’ll need to apply touch-up paint. Be sure to:
-
Get the exact color match (check your car’s paint code, often found in the door jamb or owner’s manual).
-
Shake the touch-up pen or bottle thoroughly before use.
-
Apply in thin, even layers using a fine brush or applicator.
Let each coat dry before adding another (usually 20–30 minutes).
Step 6: Apply Clear Coat
Once the paint has dried, seal it with a clear coat. This restores the glossy finish and protects the area from UV damage and moisture.
Apply a thin layer over the painted section and let it cure for at least 24 hours.
Step 7: Polish the Area
Use a fine polishing compound to blend the repaired area with the surrounding paint. Apply in a circular motion using a soft applicator pad.
Buff the area with a clean microfiber cloth until it shines.
Step 8: Wax for Protection
Finish the job by applying a high-quality car wax to the area. This adds a protective layer and helps the repair blend even further.
When to Avoid DIY Scratch Repairs
While most surface scratches are DIY-friendly, there are times when it’s best to consult a professional:
-
Multiple deep scratches
-
Cracked or peeling paint
-
Large dent combined with paint damage
-
Rust beginning to form
Attempting to fix these yourself may lead to more noticeable imperfections or long-term damage.
Final Thoughts: Save Money and Maintain Value
With the right tools, patience, and attention to detail, DIY scratch repair can save you hundreds of pounds or dollars in body shop fees. Whether you’re preparing your car for resale, returning a leased vehicle, or just want to keep it looking sharp, tackling small scratches at home is entirely doable.
Just remember: not all scratches are created equal. Take time to assess the damage, follow the right steps, and always work in a clean, shaded environment. Your car—and your wallet—will thank you.
