What Is Car Paint?

Car paint is more than just colour. It’s a protective system designed to shield your car’s body from rust, weather, UV damage and everyday wear. A modern car paint system usually consists of multiple layers:

  • Primer – helps paint stick to the surface and prevents corrosion
  • Base coat (colour) – provides the visible colour of the car
  • Clear coat (lacquer) – adds gloss and protects the colour

Types of Car Paint

There are several types of car paint used today. Knowing the difference helps you choose the right one for your car paint repair or respray.

Solid Car Paint

Solid colours are non-metallic and are often easier to match and repair.

Metallic Car Paint

Metallic paint contains small metal flakes that reflect light, giving a sparkle effect.

Pearl Car Paint

Pearl finishes use special pigments to create depth and colour-shifting effects.

1K vs 2K Car Paint (What Most People Mean by “Car Spray Paint”)

  • 1K paint – easiest to use for DIY and “paint car at home” projects
  • 2K paint – tougher, more durable and closer to bodyshop quality

How to Paint a Car (Step-by-Step Overview)

If you’re planning to paint your car at home, preparation and patience are key. Here’s a simple overview of the process.

1️⃣ Preparation

  • Wash the car thoroughly and dry it
  • Remove wax/grease with panel wipe or degreaser
  • Sand damaged or uneven areas until smooth
  • Feather edges so old and new paint blend
  • Mask trims, lights and edges you don’t want painted

2️⃣ Primer

  • Apply primer on bare metal, filler or deep scratches
  • Use light coats and allow to dry fully
  • Lightly sand primer if needed for a smooth base

3️⃣ Apply Colour (Base Coat)

  • Shake the can well (1–2 minutes)
  • Apply light, even coats (don’t flood the panel)
  • Allow flash time between coats
  • Build coverage slowly for a smoother finish

4️⃣ Apply Clear Coat (Lacquer)

  • Apply 2–3 coats of lacquer for gloss and protection
  • Allow proper flash time between coats
  • Let it cure fully before polishing
Best results tip: If your colour match is correct but the finish looks “patchy”, it’s usually application technique (distance, coat thickness, overlap) rather than the paint itself.

Car Paint Colours & Colour Matching

Choosing the right car paint colour is crucial. Even similar-looking colours can have multiple variants depending on manufacturer, year and finish.

For the best blend, always use colour matched paint made for your exact vehicle.

Common Car Paint Mistakes to Avoid

  • Skipping preparation or sanding
  • Spraying too close or applying coats too heavy (runs)
  • Not allowing enough drying/flash time
  • Painting in cold, damp or dusty conditions
  • Forgetting lacquer / clear coat protection

DIY vs Professional Car Paint Repairs

DIY Car Paint

DIY is ideal for scratches, chips and localised repairs where you want to improve the look and protect the panel.

Professional Car Paint

Professional resprays are best for large areas, complex pearl finishes, or when you need a near-perfect factory finish.

FAQs

Do I need my paint code to buy car spray paint?

No — with ScratchRepairCar you can simply enter your registration number on the product page and we’ll match the paint for you.

Is 1K or 2K spray paint better?

1K is easier for DIY and small repairs. 2K is tougher and more durable, closer to a professional finish.

How do I avoid a mismatched repair?

Use colour matched paint for your car and apply light, even coats. The biggest causes of visible repairs are heavy coats, poor blending and skipping lacquer.

Do I need lacquer (clear coat) after spraying colour?

Yes — lacquer protects the colour coat and gives gloss and durability. Most modern car paint systems rely on clear coat for protection.

Can I paint my car at home?

Yes. Many people successfully repair scratches and small panels at home. The key is prep, correct products, and allowing proper drying time.
