Car scratches are unsightly and can impact the resale value of your vehicle. Luckily, there are many ways to remove them without taking your car into a shop. To determine the best method, you must first assess the depth of the scratch. A simple fingernail test can help you do this: if your nail passes over the scratch without snagging, it's a shallow scratch; if your nail snags, it's a deeper scratch. Shallow scratches can often be buffed out with toothpaste, a scratch removal product, or a clear coat pen or spray. Deeper scratches may require sanding, repainting, and other methods, which are best left to professionals.

What You'll Learn
Use toothpaste to buff out surface scratches
Using toothpaste to buff out surface scratches on your car is a popular DIY hack because it is cheap and simple. Toothpaste is a mild abrasive, so it can help smooth out scratches by buffing the problem area. However, toothpaste is not as effective on car surfaces as it is on softer surfaces, such as CDs or DVDs, because the clear coats on cars are much harder.
To remove nail scratches from your car using toothpaste, start by cleaning your car exterior. Then, apply a small amount of toothpaste to a clean microfiber towel or a soft cloth. Never apply toothpaste directly to the scratch. Rub the cloth on the scratch carefully in a circular motion, without applying too much pressure, as this can cause further damage. After that, make sure you fill the entire scratch with toothpaste. If you are working in the sunshine, use a damp cloth.
Once you have filled the scratch with toothpaste, use a clean, damp cloth to remove the excess toothpaste. Repeat this process until all the toothpaste is gone. Check your work after each pass. Keep in mind that the more you rub, the more of the clear coat comes off, which can damage your car's paint over time.
While toothpaste can be used to remove clear coat scratches, it is not effective on deep scratches. If the scratch is deep, you may need to sand and repaint the area, which is typically best handled by professionals.

Apply a clear coat pen or clear nail polish
If you've discovered nail scratches on your car, don't panic—it's often an easy and cheap fix, especially if the scratch is minor. Firstly, assess the depth of the scratch by running your fingernail across it. If your nail passes over the scratch without snagging, it's likely a minor scratch that you can repair yourself. If your nail snags, it's a deeper scratch, and you may need a professional scratch removal product.
For minor scratches, you can use a clear coat pen or clear nail polish to fill in the scratch. A clear coat pen applies a thin layer of clear coat to the scratch, and it costs about $16. If you don't have a clear coat pen, you can use a small amount of clear nail polish, but the results may not be as accurate.
When using a clear coat pen, apply it gently to the scratch, being careful not to apply too much pressure, as this could damage the clear coat. If using clear nail polish, spray or apply a small amount directly onto the scratch and allow it to dry. Once it's dry, buff away any excess polish with a clean, soft microfiber cloth.
It's important to note that this method is most effective for minor scratches that haven't exposed the underlying metal of your car. If you can see the metal, you may need to sand and repaint the area, which is a more complex process that may require professional help.
Additionally, before applying any products to your car, ensure that the scratched area is clean and free of dirt and debris. This will help prevent further scratches and ensure the best results when applying the clear coat pen or nail polish.

Sand down the area around the scratch
Sanding down the area around a scratch is a recommended method for removing deep scratches from your car. Before you begin, it's important to wash your car so that you're starting with a clean surface. You can do this yourself by spraying your car with a hose to remove dirt and debris, then using a sponge or brush meant for washing cars to apply soap formulated for vehicles.
Once your car is clean and dry, you can start sanding down the area around the scratch. It's important to remember not to sand in the opposite direction of the scratch, as this will only create more scratches. For deep scratches, you may need to use a wet sanding process with fine sandpaper. Dunk your sandpaper in water periodically as you sand.
After sanding, you'll need to buff and polish the area using a buffing compound and polishing compound, respectively, and different pads for each process. If the scratch has exposed the primer, you'll need to repaint the panel. To do this, you'll need masking tape, automotive primer, base coat paint that matches your car's colour, a top coat product, and a polishing cloth. Tape off the area around the scratch, then apply the primer and wait for it to dry. Once the primer is dry, apply the base coat paint, followed by the top coat product. Finally, use the polishing cloth to polish the area and remove any excess paint.

Use a car scratch repair kit
Car scratch repair kits are available at auto supply stores or in the auto supply section of large one-stop shops. These kits typically include a scratch-removal solution and a buffing pad to apply the product. The cost of these kits ranges from $20 to $30. While the contents may differ by brand, you can generally expect to find the following items in a car scratch repair kit:
- Smooth putty to fill in the scratch
- A liquid leveller to remove excess putty
- A clear coat applicator
- Ultrafine sandpaper to wet-sand and remove any uneven lacquer
Before using a car scratch repair kit, it is important to wash and dry your car thoroughly. This will ensure that the scratched area is clean and free of dirt and debris, which can worsen the scratches if they are rubbed into the paint.
To use the car scratch repair kit, start by applying a small amount of the scratch remover to a microfibre towel. Spread the product over the scratch and a surrounding area of about 60 cm. Rub in overlapping circular motions with moderate pressure for about 60 seconds. If the scratch is deep, you may need to use a more abrasive cutting compound.
After applying the scratch remover, use the liquid leveller from your kit to remove any excess putty. Then, apply the clear coat with the provided applicator. Once the area is dry, use the ultrafine sandpaper to gently wet-sand any uneven areas. This will help to create a smooth and level surface.
If the scratch is particularly deep, you may need to take additional steps. After using the car scratch repair kit, you may need to repaint the area. To do this, you will need masking tape, automotive primer, base coat paint that matches your car's colour, a top coat product, a polishing compound, and a polishing cloth.
By following these steps and using a car scratch repair kit, you can effectively remove nail scratches from your car and restore its appearance.

Repaint deep scratches
If you have deep scratches on your car, it is recommended that you consult an expert or take your car to a local body shop. Deep scratches can expose the bare metal of your car, which can lead to rusting if left unprotected.
However, if you want to repaint deep scratches yourself, here is a general guide:
First, wash your car to ensure you are working on a clean surface. Next, sand down the area around the scratch with fine sandpaper until you can see the metal. Remember to sand in the same direction as the scratch to avoid causing further damage. For this process, you may need to use a wet sanding technique, periodically dunking your sandpaper in water.
Once the area is sufficiently sanded, you can begin to buff and polish the scratch. Use a buffing compound and polishing compounds with different pads for each process. After you have finished buffing and polishing, the area should be prepped for painting. Use masking tape and paper to section off the area, then apply automotive primer and wait for it to dry.
Finally, you can apply a fresh coat of paint to the area. Be sure to use a paint colour that matches the rest of your car. You may also want to consider using a clear coat pen or spray to add a thin layer of protection over the new paint.
