If your fingernail does not catch on the scratch, it is most likely only in the clear coat; you can fix it yourself with polishing or a small touch-up. If your fingernail catches, or a grey or metal base is visible, it has reached the paint and a touch-up pen will not be a lasting solution; workshop touch-up or spot repair painting is needed. We handle this in 1–3 days at our workshop in Kepez Akdeniz Sanayi industrial estate, providing quick estimates by photo.
Fingernail test: how deep is the scratch?
This method is the most practical way to determine which layer the scratch has reached. Wash and dry the vehicle, then run your fingernail perpendicular across the scratch.
| Fingernail test result | Likely condition | What to do? |
|---|---|---|
| Does not catch at all | Fine scratch only in the clear coat layer | Machine polishing; if very minor, you can try it yourself |
| Catches slightly | Clear coat penetrated, paint layer may be affected | Touch-up or spot repair painting |
| Catches clearly, grey or metal visible | Paint and primer penetrated, bare metal exposed | Body filler, primer, and paint required; have it repaired before rust forms |
Tip: Scratches may look deeper or fainter when wet. Perform the test on a clean, dry surface in daylight. If a scratch disappears when wet and reappears when dry, it means water is temporarily filling the groove; verify it with the fingernail test.
When is touch-up paint enough?
Touch-up is the process of applying a small amount of paint inside a scratch or stone chip to cover the missing color. Store-bought touch-up pens and paints are the DIY version of this. The honest answer: in some cases it helps, in others it makes things worse.
When you can do it yourself
- If the scratch is very small (like a tiny stone chip) and bare metal is exposed, as temporary protection to delay rust
- For minor marks not visible from a distance with the naked eye, noticeable only up close
- If vehicle aesthetics are not your priority and the main goal is protecting the metal
When you should have it done at a workshop
- If the scratch is long, wide, or there are multiple scratches on the panel
- If metallic or pearlescent flakes show a visible contrast; touch-up paint applied with a pen cannot match the flake texture
- If the scratch is in a prominent spot, such as door surfaces or bumper corners
- If you plan to sell or get the vehicle inspected; a poorly applied touch-up looks like an unsightly blemish that is hard to remove later
Warning: Smearing touch-up paint over the edges makes the scratch look larger and complicates future spot repair painting. If you apply it, use a minimal amount strictly inside the groove.
How is scratch repair and touch-up done in a workshop?
The difference between a touch-up and spot repair painting in the workshop is the scope of the repair. For very small marks, touch-up is used; when a scratch is long or wide, spot repair painting is applied, where the damaged area is painted and blended into the surrounding panels.
- Depth assessmentThe scratch is inspected to determine whether it is in the clear coat, paint, or bare metal.
- Method selectionIf it is a clear coat scratch, machine polishing is selected; if it reached the paint, touch-up or spot repair painting; if bare metal is exposed, body filler and primer are planned.
- Color formulationPaint is mixed according to the vehicle's color code and adjusted with digital color matching to match its current shade.
- ApplicationPPG or Standox paint is applied in a dust-free booth; borders are blended smoothly into surrounding areas.
- Inspection and deliveryThe finished surface is inspected under daylight.
Which scratches do customers come to us for?
- Parking scuffs: Scuff marks on bumper and door corners. Because the scratches are usually localized, they are resolved with spot repair painting.
- Stone chips: Small chips on the front of the hood; if bare metal is exposed, it is best to repair them before rust sets in.
- Key scratches: Long and deep scratches usually cut through the paint; they require spot repair painting or full panel painting.
- Wash-induced swirl marks: Most are clear coat scratches and diminish with polishing. See our article on scratches caused by improper car washing for details.
If you are looking for a general guide on scratch removal, our article on the fingernail test and scratch repair explains the methods in detail. For small dents and plastic damage caused by scuffs, you can also check our bodywork repair page.
Duration and pricing
Minor damage usually takes 1–3 days. Pricing varies depending on the scratch length, depth, and how many scratches are on the panel; as a reference for full panel painting, door painting ranges from 3,500–6,000 TL and bumper painting ranges from 2,500–5,000 TL. Scratches repaired with spot repair painting may cost less. We can give an estimate from photos; in-person inspection at our workshop is free.
Send a photo of the scratch, and we will tell you whether it needs touch-up or spot repair painting, along with an initial estimate. Workshop inspection is free.
Common mistakes in scratch and touch-up repairs
- Applying body filler directly over scratches: Over-the-counter scratch removal pastes only work temporarily on clear coat scratches. On deep scratches, they merely mask the damage, which reappears after a few car washes.
- Trying to sand it out yourself: When the clear coat is thin, improper sanding cuts right into the paint layer, turning a minor issue into a spot repair painting job at the workshop.
- Applying touch-up paint too thick: As it dries, it forms an elevated bump over the scratch that looks like a shiny blemish.
- Leaving exposed metal untreated: In humid conditions, bare metal quickly begins to rust, leading to much larger repair costs.
- Ignoring color tone differences: On an older or sun-faded car, paint mixed strictly to the original factory code will look noticeably different side by side. That is why shading and tinting to match the current color is essential.
How to minimize scratch formation
Most scratches occur during washing: wiping with a dry cloth, using a dirty sponge, or washing over dry dust leaves fine swirl marks in the clear coat. Pre-rinsing with plenty of water to loosen dirt, using clean microfiber cloths, and wiping in straight lines rather than circular motions minimizes these swirls. Leaving ample space on the door-opening side when parking also reduces parking scuffs.
What to expect based on scratch type
Although scratches may look similar, their origins differ, and repair methods vary accordingly.
- Wash swirls: Circular, fine lines visible under direct light. Usually diminished significantly with machine polishing.
- Fingernail scratches (around door handles): Scratches in the door handle recess caused by fingernails are shallow; most remain within the clear coat layer.
- Scuff transfer marks: Paint transferred from another vehicle or a wall. The transferred paint must be cleaned off first before evaluating the underlying scratch.
- Stone chips: Small, pinpoint chips that often pierce through the paint; typically found on the front hood and upper bumper.
- Deep scuffs and key scratches: Cut through the paint and primer, exposing bare metal. Workshop repair is required.
If there is transferred paint from a scuff, the true depth of the scratch only becomes apparent after cleaning. Many scuffs that look severe turn out to be much lighter once paint transfer is removed; washing the vehicle and checking it once more in daylight is an easy check before heading to a workshop.
Tip: If you are considering a touch-up, bring the vehicle without sanding or applying filler yourself. An untouched surface allows us to accurately assess the depth.
Frequently asked questions about scratch repair and touch-up
Is a touch-up pen enough for scratches?
It only works for very small marks and to temporarily protect the bare metal. Because metallic flake, shade, and surface smoothness cannot be matched with a pen, it is not a permanent solution for visible scratches that reach the paint layer.
How is the fingernail test done?
Dry the vehicle and run your fingernail perpendicular across the scratch. If it does not catch, the scratch is most likely only in the clear coat; if it catches, it has penetrated into the paint layer. If a grey or metallic base is visible, the bare metal is exposed.
Do scratch remover paste or polishing compound work?
They are only effective on shallow scratches in the clear coat layer. For a scratch that has reached the paint layer, they only provide a temporary effect and are not a permanent solution.
Can key scratches be repaired?
Yes. Because deep and long scratches usually penetrate through the paint, they require spot repair painting or full panel painting. Once we see the damage, we will tell you which method is best.
Touch-up or spot repair painting?
Touch-up may be sufficient for tiny, pinhead-sized marks. If the scratch is long or there are multiple scratches on the panel, spot repair painting is applied.
How long does scratch repair take?
Minor damage usually takes 1–3 days. We give an exact timeframe after assessing the damage.
What happens if a scratch is not repaired?
If the paint layer is penetrated and bare metal is exposed, rust can develop over time and repair costs will increase. Shallow clear coat scratches are merely a cosmetic issue.
