When driving on the road, your paint surface inevitably suffers various kinds of “damage”: branches scraping, swirl marks from washing, small scratches from door impacts… Do these annoying marks require a professional shop? Actually, for most light scratches, you can repair them yourself.
Step 1: Correctly Assess Scratch Depth
Observation Methods
- Touch Test: Gently run your fingernail across the scratch
- Fingernail catches in the groove → Damage reaches the base coat
- Fingernail feels smooth → Only the clear coat is affected
-
Visual Inspection: Observe under strong light
- Scratch appears white → Only clear coat affected
- Scratch reveals base color → Damage reaches base coat or metal
-
Water Drop Test: Place a drop of water on the scratch
- Scratch disappears → Surface contamination only
- Scratch remains → Genuine damage
Scratch Classification
| Type | Depth | Repair Difficulty | Required Products |
|---|---|---|---|
| Contamination marks | Surface | Simple | Car wash soap |
| Swirl marks | Clear coat | Relatively simple | Fine wax / polishing compound |
| Light scratches | Clear coat | Moderate | Cutting compound |
| Moderate scratches | Base coat | Difficult | Touch-up paint + polishing |
| Severe scratches | Metal layer | Very difficult | Professional repair |
Important: Scratches that reach the base coat should be treated professionally, especially when metal is exposed, due to rust risk.
