Does paint correction remove all scratches?

No, paint correction cannot remove all scratches. It can remove or significantly reduce most scratches in the clear coat, but there's a limit to how much clear coat can be safely removed. Modern car paint has about 2-3 mils of clear coat. Deep scratches to bare metal, paint chips, and dents cannot be fixed with paint correction alone.

What is the difference between paint correction and scratch fillers?

Paint correction actually removes scratches by leveling the clear coat, providing permanent results until new damage occurs. Scratch fillers and glazes temporarily fill in scratches to hide them but wash away over time. Paint correction is the real fix, while fillers are temporary solutions.

Does paint correction fix deep scratches?

Paint correction can improve deep scratches in the clear coat but may not remove them entirely if they're too deep. Scratches that go through to the base coat, primer, or bare metal cannot be fixed with paint correction alone and require touch-up paint or professional repainting first.

Can Paint Correction Fix Scratches? What You Need to Know

If you've noticed scratches on your car's paint, you're probably wondering if paint correction can fix them. The answer depends on how deep the scratch is.

Here's the quick answer: Paint correction can remove light to moderate scratches that only affect the clear coat. Deep scratches that reach the base coat or primer usually can't be fixed with paint correction alone—they need touch-up paint or repainting.

Let's break down exactly which scratches paint correction can handle and what you can expect from the process.

How Deep Is Your Scratch? (The Fingernail Test)

Before you decide on paint correction, you need to know what you're dealing with.

Run your fingernail gently across the scratch:

Can't feel it at all? That's surface-level damage (swirl marks, light scratches). Paint correction will fix this easily.
Feel a slight catch? This is a clear coat scratch. Paint correction can usually remove it completely.
Your nail catches and drags? The scratch is deeper—it might have gone through the clear coat into the paint layer. Paint correction can improve it but may not remove it entirely.
You can see white or primer underneath? This scratch is too deep for paint correction. You'll need touch-up paint or professional repainting.

What Paint Correction Can Actually Fix

Paint correction works by carefully removing a thin layer of your car's clear coat to level out imperfections. Here's what typically responds well:

Light Surface Scratches

These are the most common—caused by automated car washes, improper drying, or light contact with objects. They sit entirely in the clear coat and can usually be removed completely with a single-stage paint correction.

Swirl Marks

Those spider-web patterns you see under direct sunlight? They're actually thousands of tiny scratches. They happen from washing with dirty towels, using the wrong products, or taking your car through brush-style car washes. A good polishing treatment can eliminate them.

Water Spots and Etching

Hard water, bird droppings, and tree sap can etch into your clear coat, creating marks that look like scratches. Paint correction can smooth these out if caught early enough.

Oxidation and Fading

Sun damage creates a dull, chalky appearance on your paint. While not technically scratches, paint correction removes the oxidized layer to reveal fresh, glossy paint underneath. For severe cases, check out our oxidation removal service.

Random Deep Marring

Those random scuff marks from shopping carts, door dings, or parking mishaps—if they haven't broken through the clear coat, paint correction can usually handle them.

What Paint Correction Can't Fix

Be realistic about what's possible. Paint correction has limits:

Deep scratches to bare metal - These need touch-up paint first
Chips in the paint - Rock chips or impact damage won't respond to polishing
Dents - Paint correction is only for surface-level issues
Repainting mistakes - Orange peel texture or runs in the paint need wet sanding or repainting

If your scratches are too deep, we'll be honest with you. Sometimes paint protection film (PPF) after touch-up work is a better option for protecting vulnerable areas from future damage.

The Paint Correction Process for Scratch Removal

Here's how we approach scratch removal at Nor Bay Mobile Detailing:

Step 1: Wash and Decontaminate
We start with a thorough hand wash, followed by a clay bar treatment to remove embedded contaminants. This ensures we're only polishing the paint, not grinding dirt into it.

Step 2: Inspect Under Proper Lighting
We use high-intensity LED lights to identify every scratch, swirl mark, and imperfection. This tells us exactly how aggressive we need to be.

Step 3: Test and Correct
We test our approach on a small section first. Depending on the severity of your scratches, we might use:

A cutting compound for deeper scratches
A medium polish for moderate imperfections
A finishing polish for the final refinement

We work panel by panel, removing just enough clear coat to level the surface without going too thin.

Step 4: Protection
Once your paint is corrected, it's vulnerable. We strongly recommend protecting it with either ceramic coating for long-term protection or at minimum a quality wax to seal the paint.

How Many Stages of Paint Correction Do You Need?

The depth and extent of your scratches determines how intensive the process needs to be:

Single-Stage Correction - For light swirls and minor scratches. Uses one polish to refine the paint. Good for newer cars or vehicles that have been well-maintained.

Two-Stage Correction - For moderate scratches and swirl marks. Uses a cutting compound followed by a finishing polish. This is what most cars need.

Multi-Stage Correction - For heavily scratched or neglected paint. Involves multiple compounds and polishes to progressively remove deeper scratches. This is intensive work that takes time.

Will Paint Correction Remove All Scratches?

No, and anyone who promises that isn't being straight with you.

Paint correction can remove or significantly reduce most scratches that are only in the clear coat. But there's always a limit to how much clear coat we can safely remove. Modern car paint typically has about 2-3 mils (thousandths of an inch) of clear coat. We measure the thickness before we start and never remove more than is safe.

If your car has had paint correction done multiple times before, there might not be enough clear coat left to work with.

Paint Correction vs. Other Scratch Fixes

Paint Correction - Actually removes scratches by leveling the clear coat. Results last until new damage occurs. This is the real fix.

Scratch Fillers/Glazes - These products temporarily fill in scratches to hide them. They wash away over time. They're not a permanent solution.

Touch-Up Paint - Necessary for scratches that go through to the primer or metal. Works for chips and deep gouges that paint correction can't reach.

Wet Sanding - More aggressive than standard paint correction. Used for severe defects like orange peel texture or really deep scratches. Requires expert skill.

How Long Does Paint Correction Last?

Once scratches are removed, they're gone. But your car will get new scratches over time unless you protect it.

How long your correction lasts depends on:

How you wash your car (hand washing is best)
Whether you apply protection afterward
Where you park (garage vs. outside)
How often you drive

Most people pair paint correction with ceramic coating to protect the fresh paint. Ceramic coating creates a hard, glossy layer that resists light scratches and makes the car much easier to keep clean.

Without protection, you might see new swirl marks within a few months—especially if you're still using automated car washes.

Should You Get Paint Correction for Scratches?

Paint correction makes sense if:

Your car has noticeable swirl marks or light scratches
The paint looks dull or hazy from oxidation
You want to restore the car before selling it (it increases resale value)
You're planning to apply ceramic coating (you want perfect paint underneath)
The scratches bother you and you want them gone

It might not be worth it if:

The scratches are too deep (going into the base coat)
Your car is very old and you're not worried about appearance
You're planning to repaint the car anyway
Your budget is tight (a good detail with wax might be enough)
