## 🚗 Why You Should Fix Paint Chips Quickly
Paint chips expose the bare metal (or primer) underneath your car’s paint. When that happens:
– 💧 **Moisture reaches the metal** → leads to rust.
– ☀️ **UV light damages the exposed surface** → can cause fading and peeling.
– 🧪 **Road salt and chemicals** accelerate corrosion in winter climates.
– 💰 **Resale value drops** if visible chips and rust spots build up.
Taking care of chips early is one of the simplest and cheapest ways to protect your car’s appearance and value.

## 🎨 Step 1: Identify The Type Of Paint Chip
Not all chips are the same. Understanding what you’re dealing with helps you choose the right approach.
### 1.1 Small Surface Chips
– Size: Pinhead to a few millimeters across
– Depth: Usually through the clear coat and color layer, sometimes down to primer
– Common cause: Highway debris, small stones
➡️ These are the easiest to fix with basic touch-up paint.
### 1.2 Medium Chips
– Size: Up to a fingernail or a bit larger
– Depth: Often down to bare metal or plastic
– Common cause: Larger stones, door dings, scraping objects
➡️ These need more prep, possibly primer and multiple layers of touch-up paint.
### 1.3 Large Chips & Scrapes
– Size: Larger areas, lines, or multiple clustered chips
– Depth: Down to metal or plastic, sometimes with light denting
– Common cause: Parking lot accidents, deep scratches
➡️ These may require filler, sanding, and more advanced blending. For very large areas, a body shop may be more practical.

## 🧼 Step 2: Clean & Prep The Area
Proper preparation is 80% of a good repair. Don’t rush this step.
### 2.1 Wash The Area
1. Mix **car shampoo** with clean water.
2. Wash thoroughly around the chipped area to remove:
– Dirt
– Road grime
– Old wax or sealant residues
3. Rinse and dry with a **clean microfiber towel**.
> Tip: Work on a cool, dry surface in the shade. Heat or direct sun can cause paint or clear coat to dry too fast and leave marks.
### 2.2 Degrease & Decontaminate
1. Soak a **lint-free cloth** or microfiber in **rubbing alcohol or wax & grease remover**.
2. Gently wipe the chipped area and a small perimeter around it.
3. Let it air-dry completely.
This step ensures there’s no residue that will prevent the new paint from bonding correctly.

## 🔍 Step 3: Remove Loose Paint & Rust
A common mistake is painting over damaged or loose material. You want a clean, solid base.
### 3.1 Inspect The Chip
Use:
– A **flashlight or headlamp**
– A **magnifying glass** (optional)
Check for:
– Lifted edges of paint
– Flaking or peeling clear coat
– Any visible rust (brown or orange discoloration)
### 3.2 Remove Loose Paint
Use:
– A **plastic trim tool**
– A **plastic razor blade**
– Or even a **toothpick**
Carefully:
1. Pick at the loose edges of paint within the chip.
2. Remove any flakes that are not firmly attached.
3. Avoid scratching the surrounding good paint.
### 3.3 Sand Rusted or Rough Areas
If rust is present:
1. Use **fine-grit sandpaper (1000–1500 grit)**.
2. Gently sand within the chip until:
– Rust is completely removed.
– The surface feels smooth to the touch.
3. If rust is deep or pitted, you may need a **rust converter** (follow product instructions).
Wipe the area with a **tack cloth** or lint-free cloth to remove dust.

## 🧱 Step 4: Build A Smooth Base (Primer & Filler)
For chips that reach bare metal or are deeper than a simple surface scratch, you need a solid base coat.
### 4.1 When You Need Primer
Use primer if:
– Bare metal or plastic is exposed.
– The chip is deeper than the surrounding paint.
– The manufacturer of the touch-up paint recommends it.
### 4.2 Applying Primer
1. Mask around the chip using **automotive masking tape** to avoid overspray or extra mess.
2. If using:
– **Primer pen/brush**: Dab a thin layer directly into the chip.
– **Spray primer**: Spray a little into the can’s cap or onto a clean surface, and use a small brush or micro applicator to apply.
3. Apply **very thin layers**, allowing each layer to dry per the product instructions (often 15–30 minutes).
🔁 Repeat until the chip’s base is covered but not overfilled.
### 4.3 Using Glazing Putty or Filler (For Larger Chips)
For chips that are more like shallow craters:
1. Apply a **small amount of glazing putty** using a plastic spreader.
2. Smooth it across the chip, pressing it into the low area.
3. Let it dry completely.
4. Sand lightly with **1500–2000 grit** sandpaper until it’s level with the surrounding paint.
Wipe clean with a tack cloth and a bit of alcohol/wax remover.

## 🎯 Step 5: Match & Prepare Your Touch-Up Paint
Getting the right color is crucial to making the repair as invisible as possible.
### 5.1 Find Your Car’s Paint Code
Look for a label or sticker in one of these locations:
– Driver’s side door jamb
– Under the hood (radiator support or strut tower)
– Inside the glove box
– In the trunk (spare tire area)
The **paint code** is typically:
– A combination of letters and numbers, like:
– `PXR`, `U 8554`, `NH-731P`, etc.
Use this code to order:
– **OEM touch-up paint** from the dealer or manufacturer
– Or compatible paint from reputable third-party brands
### 5.2 Types of Touch-Up Paint
– 🖊️ **Paint pen**: Great for thin chips and scratches.
– 🖌️ **Brush bottle**: Good for larger chips and small areas.
– 💨 **Spray can**: Better for larger sections; usually requires more advanced blending.
For most small to medium chips, a **pen or small brush bottle** works best.

## 🎨 Step 6: Apply Color Coat (Touch-Up Paint)
This is where the visual magic happens. Patience and thin layers are the key.
### 6.1 General Rules
– Shake the paint well (usually 1–2 minutes).
– Test on a piece of cardboard or hidden area first.
– Work in thin, controlled layers.
### 6.2 For Small Chips
Using a **touch-up pen or micro brush**:
1. Lightly dab the paint into the center of the chip.
2. Let surface tension pull it outwards to fill the chip.
3. Don’t try to fill it all at once. Aim for:
– 2–4 thin layers
– Allowing each layer to dry (often 20–30 minutes) before the next
### 6.3 For Medium Chips
Using a **small brush**:
1. Load just a tiny amount of paint on the brush tip.
2. Touch the lowest part of the chip and let the paint flow.
3. Carefully “level” the paint across the chip, but do not spread it onto surrounding good paint.
4. Build up layers slowly until the color level is close to the original paint.
> Tip: If you accidentally overfill, wait until it fully cures, then very lightly wet-sand and polish (we’ll cover this later).

## ✨ Step 7: Apply Clear Coat
Clear coat protects the color and adds gloss, blending your repair with the rest of the panel.
### 7.1 When To Use Clear Coat
– Most modern cars use a **basecoat (color) + clear coat** system.
– If your touch-up paint is not labeled as “single-stage,” you should apply a clear coat on top.
### 7.2 How To Apply Clear Coat
1. Ensure the color coat is fully dry.
2. Use a **clear coat pen** or **small brush** for best control.
3. Apply a very thin layer, just covering the painted area.
4. Allow it to dry, then add another layer if needed.
Goal: Build the clear coat slightly **higher** than the surrounding paint. Later, you can level and polish it flat with the rest of the surface.

## 🧽 Step 8: Level & Blend The Repair
This is the step that takes your repair from “visible touch-up” to “hard to notice.”
### 8.1 Curing Time
Before leveling:
– Let the repaired area cure fully:
– Check your paint manufacturer’s recommendations.
– Typically at least **24–48 hours**, sometimes more for complete hardness.
### 8.2 Wet Sanding (Advanced But Effective)
Only if you’re comfortable and the chip was mid to large. If it’s tiny, you can skip sanding and go straight to polishing.
1. Wrap a small piece of **2000–2500 grit** sandpaper around a foam block or a rubber eraser.
2. Soak the paper in clean water with a drop of dish soap for lubrication.
3. Gently sand in small, circular motions directly over the repaired spot.
4. Frequently dry and check your progress.
Goal: Level the slightly raised repair so it’s flush with the surrounding paint, without cutting through the clear coat around it.
> Important: Go very slowly. If you see color on your sanding paper from surrounding areas, you may be going through the clear and into the color. Stop immediately.
### 8.3 Polish The Area
1. Apply a **small amount of polishing compound** to a microfiber applicator or foam pad.
2. Polish the area using:
– Small circular motions if working by hand, or
– A DA polisher set to low/medium speed.
3. Work until the sanded area becomes glossy and blends with the surrounding paint.
4. Wipe off residue with a clean microfiber towel.
Result: The surface should now feel smooth and look close to the original finish.

## 🛡️ Step 9: Protect With Wax or Sealant
After polishing, you’ve restored the look; now protect your work.
1. Ensure the area is **clean and dry**.
2. Apply a **quality car wax or paint sealant** to the repaired spot and surrounding panel.
3. Let it haze (if wax), then buff with a soft microfiber towel.
This adds:
– Extra shine
– UV protection
– A barrier against moisture and contaminants
