To polish carbon fiber car panels, start by washing the car to remove any dirt or debris. Then, use a polishing compound and a microfiber cloth to gently buff the panels until they shine.

When it comes to maintaining the appearance of your car, carbon fiber panels require special care and attention. If not cleaned and polished correctly, the clear coat on the panels can become hazy and dull over time. This is why it’s essential to use the appropriate method when polishing them.

Carbon fiber panels are known for their unique appearance, which can provide your vehicle with a sporty and futuristic look. But to keep them looking their best, you must maintain them properly. In this article, we’ll cover how to polish carbon fiber car panels effectively.

Understanding Carbon Fiber Car Panels

What Is Carbon Fiber?

Carbon fiber is a composite material used in many industries, including automotive and aerospace manufacturing, due to its desirable properties, such as high strength-to-weight ratio, durability, and stiffness. In the automotive world, carbon fiber has become popular due to its aesthetic appeal and lightweight properties.

Carbon fiber car panels are made from sheets of carbon fibers that are arranged in a specific pattern and bonded together with resin.

Pros And Cons Of Carbon Fiber Car Panels


  • Lightweight: Carbon fiber car panels weigh less than traditional steel panels, which reduces the overall weight of the vehicle, increasing fuel efficiency and performance.
  • Aesthetic appeal: Carbon fiber car panels add a sleek and modern look to a vehicle. They can be customized with various patterns and colors to create a unique design that stands out.
  • Durability: Carbon fiber car panels are highly durable and resistant to corrosion, making them ideal for cars exposed to harsh weather conditions.
  • Stiffness: Carbon fiber car panels offer high stiffness, which translates to better handling and stability on the road.


  • Expensive: Carbon fiber car panels can be very expensive, and repairs are also costly due to the specialized equipment and techniques required.
  • Difficulty in repair: Although highly durable, carbon fiber car panels are difficult to repair, and the process requires specialized skills and knowledge.
  • Fragility: Carbon fiber car panels are prone to cracking and chipping under impact, which can compromise their integrity and require replacement.

How To Identify Carbon Fiber Car Panels

There are several ways to identify if a car panel is made of carbon fiber, including:

  • Look for a distinctive weave pattern: Carbon fiber panels have a unique weave pattern that is not present in traditional steel panels.
  • Tap the panel: Carbon fiber car panels produce a hollow sound when tapped, unlike steel panels that produce a dull thud.
  • Examine the surface texture: Carbon fiber car panels have a distinctive surface texture that is smooth and glossy, with visible fibers woven into the pattern.
  • Check the weight: Carbon fiber car panels are considerably lighter than traditional steel panels, and you can feel the difference by lifting them.

Tools And Materials Required

Polishing carbon fiber car panels is an easy and effective way to bring the shine back to your vehicle. You need a set of tools before you start polishing. Here are a few tools and materials required to polish carbon fiber car panels.

Microfiber Towels

Microfiber towels are an important component required for polishing the car. They are made of synthetic materials such as polyester and polyamide and are known for their softness and high absorbing ability. Microfiber towels are perfect for polishing as they do not leave any scratches.

  • Use microfiber towels to collect and remove dust and debris from the surface of the car.
  • Use a clean microfiber towel to dry the area that you have just washed and to polish the panel after applying the polishing compound.


Water is the most basic requirement for polishing carbon fiber car panels. Use clean water to rinse off any dirt and grime on the surface of the car before starting to polish.

  • Use a high-pressure water hose or spray bottle to wet the surface of the car and loosen dirt and debris before wiping it off.
  • Use distilled water if the water in your area is hard. Hard water contains high levels of minerals that can damage the car’s surface.

Buffing Wheel

A buffing wheel is a tool used to apply polishing compounds to the surface of the car and to buff the surface to a shine.

  • Choose a buffing wheel that is the appropriate size for the area you are polishing. A smaller buffing wheel can help with polished edges or tight curves.
  • Attach the buffing wheel to a power drill.

Polishing Compound

A polishing compound is a chemical that has abrasive properties and is used to remove scratches and dullness from the car.

  • Apply the polishing compound using a soft, clean microfiber towel.
  • Work the compound into the surface of the car in circular motions.


Sandpaper is used to smooth out any rough spots before polishing the carbon fiber car panel.

  • Choose a fine-grit sandpaper such as 1500-2000 grit.
  • Keep the surface of the car wet while sanding to prevent scratches.

Polishing carbon fiber car panels can be a fun and satisfying task when you have all the right tools at your disposal. By following these guidelines and using the right set of tools and materials, you can restore your car’s shine and make it look brand new.

Happy polishing!

Preparing Your Car Panels For Polishing

Carbon fiber car panels look sleek and sporty when they’re polished, but before you start the polishing process, you need to prepare your car panels. Here’s how to get your car panels ready for polishing:

Washing Your Car

Before polishing your car panels, you need to give your car a thorough wash. Here are the steps to follow when washing your car:

  • Rinse off loose dirt and grime from the surface of your car with a hose
  • Fill a bucket with water and add car wash soap
  • Use a microfiber wash mitt and gently scrub the surface of your car, starting from the top and working your way down
  • Rinse off the soap with a hose
  • Dry your car using a microfiber towel

Drying Your Car

After washing your car, you need to dry it thoroughly before you can start polishing. Here’s how to dry your car properly:

  • Use a microfiber towel to pat your car dry
  • Start at the top and work your way down, making sure to dry every surface
  • Make sure to dry the corners and crevices of your car thoroughly to prevent water spots

Sanding Down Imperfections

To get the best results when polishing your carbon fiber car panels, it’s important to remove any imperfections from the surface. Here’s how to sand down any imperfections:

  • Use a fine-grit sandpaper (800 grit or higher) to sand down any raised imperfections like scratches or chips
  • Sand in a circular motion until the imperfection is level with the surrounding surface
  • Use a coarser grit sandpaper (600 grit or lower) to sand down any lower imperfections like pits or dents
  • Sand until the imperfection is level with the surrounding surface

Removing Scratches

After sanding down any scratches, you can follow these steps to further remove scratches:

  • Apply a dedicated scratch remover following manufacturer instructions
  • Use a circular motion to evenly apply a small amount of the product on the scratch
  • Buff the area with a clean microfiber cloth until the scratch is no longer visible
  • Repeat the process for each scratch

By following these steps, you can prepare your carbon fiber car panels for polishing. With clean and imperfection-free panels, you’ll be able to achieve a mirror-like shine when you start polishing.
