Car Scratches: Classifying Severity and the Right Repair Cost for Each Type
Guide to classifying car scratches by depth (surface, medium, deep) and choosing the right repair method and cost for each.
The short version
Surface-scratch polishing costs SAR 50-150 ($13-40) at a detailing shop, or under SAR 100 ($27) doable at home with basic equipment.

The short answer
- A light surface scratch visible only in the clear coat that you can't feel with a fingernail
- Contact with tree branches or a narrow wall while driving or parking
- Test scratch depth by gently running a fingernail over it: if you can't feel it, it's surface-only in the clear coat
- Gently run your fingernail over the scratch; if you feel no edge, it's surface-only in the clear coat and comes off with polishing, but if you feel a distinct edge or see a different color (gray or white) at the bottom, it's medium-to-deep and needs bigger treatment.
Background
Not all scratches are the same — some vanish with a simple polish, others need filler and a full repaint. Modern car paint consists of several layers: primer, color coat, and the top clear coat, and a scratch's depth determines which layer is affected and thus the right repair method. Knowing the difference between these levels stops you from paying for a full repair on a minor surface scratch, or settling for a temporary fix on a deep scratch that will rust later if left untreated.
Numbers first: what you'll pay
Surface-scratch polishing costs SAR 50-150 ($13-40) at a detailing shop, or under SAR 100 ($27) doable at home with basic equipment. A medium scratch with touch-up pen and light sanding costs SAR 150-400 ($40-107). A deep scratch requiring filler and a full panel repaint ranges SAR 400-1,200 ($107-320) depending on the affected area size.

How to spot it yourself
What actually causes it
- Contact with tree branches or a narrow wall while driving or parking
- Using a rough cloth or improper brush washing causing multiple fine scratches
- Deliberate or accidental scratching with a key or another sharp object
- Small gravel abrasion while driving on unpaved roads causing scattered deep scratches
Step-by-step inspection plan
- Test scratch depth by gently running a fingernail over it: if you can't feel it, it's surface-only in the clear coat
- For a surface scratch, use a rubbing compound then protective wax — often doable yourself
- For a medium scratch reaching the color but not the metal, use a matching touch-up pen then light sanding and polish
- For a deep scratch exposing metal, don't delay repair since rust starts within days in humid climates
- For multiple swirl marks, get a machine-polishing session instead of sanding
- After any paint repair, wait the recommended time before high-pressure washing or repolishing
Prevention
Wash the car with a soft microfiber cloth, not a rough sponge, avoid driving close to trees or narrow walls, apply a protective wax or ceramic coat periodically to reduce daily micro-scratch impact on the paint, and treat any deep metal-exposing scratch within a few days to prevent rust from starting.
Quick answers
How do I tell if a scratch is surface-level or deep without a shop?
Gently run your fingernail over the scratch; if you feel no edge, it's surface-only in the clear coat and comes off with polishing, but if you feel a distinct edge or see a different color (gray or white) at the bottom, it's medium-to-deep and needs bigger treatment.
Are touch-up pens actually effective?
They're effective for hiding medium scratches and preventing rust in small deep scratches, but they rarely give a perfect color and gloss match compared to professional repair, so consider them a good middle-ground fix, not a perfect one.
Why must a deep scratch be treated quickly?
Because exposed metal is directly exposed to moisture and oxygen, so rust starts within a few days in humid climates, and if rust spreads under the surrounding paint, repair becomes far more extensive and expensive than treating the original scratch alone.
Does frequent machine polishing damage the paint?
Yes, each machine-polishing session removes a very thin layer of clear coat, so repeating sessions more than two or three times a year can thin the protective layer over the long term and make the paint more vulnerable to sun damage.
