What You'll Learn
Removing the gear shift knob
To remove the gear shift knob from a 2008 Chevy Cobalt, you'll need to first lower the boot by twisting and pushing it down. There are "teeth" that need to line up with the slots before the boot can slide off. With the boot down, use a small flat-headed screwdriver to carefully bend back the pins holding the knob in place. There are four of these pins, and you'll only need to bend back two of them to remove the knob.
Alternatively, you can try prying the knob up and out with a quarter, applying pressure to the flat edges.
Once the knob is removed, you can consider switching to a new knob. Some people recommend cutting the metal shifter and welding on a threaded metal piece to make it easier to switch out knobs in the future. However, this may not be necessary if you're planning to paint the original knob and put it back in place.
If you're planning to install an aftermarket knob, keep in mind that some of them don't have threads and are held in place by set screws. You might want to purchase a new knob and boot to achieve a better look and feel.

Choosing the right paint
Painting a gear shift knob requires careful consideration of the paint type and application method. The chosen paint should be durable and suitable for the material of the gear shift knob, ensuring a long-lasting and aesthetically pleasing finish.
For aluminium gear shift knobs, it is recommended to use an etching primer before applying the top coat of your choice. Aluminium has a tendency to shed paint, so a suitable primer is crucial to ensure paint adhesion. Specifically, a ZINC Chromate primer is recommended as it not only aids in adhesion but also serves as an anti-corrosive agent, protecting the underlying metal. This type of primer is designed for aluminium and bare metal surfaces and will help prevent peeling and shedding.
If the gear shift knob is made of plastic, an adhesion promoter can be used to improve paint adhesion. Products like Dupli-Color Adhesion Promoter are suitable for both interior and exterior applications and work well with enamel and lacquer topcoats. This step is particularly important for plastic surfaces to ensure the paint properly adheres and does not chip or peel off.
When choosing the paint for the gear shift knob, consider the colour, finish, and durability. Enamel paint is a popular choice for gear shift knobs as it provides a durable finish that can withstand frequent touching and use. It is available in various colours, allowing you to match or complement the interior of your car. Enamel paint can be applied with a small brush, and multiple coats may be necessary to achieve a smooth and even finish, especially when filling in grooves or indentations.
Additionally, the paint should be able to withstand regular cleaning and exposure to various substances, such as hand sanitiser, sweat, and lotions. A clear coat or sealant can be applied on top of the paint to provide extra protection and a smooth finish. This step is crucial to ensuring the longevity of the paint job and preventing chipping or fading over time.

Using an etching primer
Painting your gear shift knob can be a great way to customize your 2008 Chevy Cobalt and make it more reflective of your personal style. If the gear shift knob is made of aluminum, one important step in the painting process is to use an etching primer.
Etching primer is specifically designed for aluminum and bare metal surfaces. It helps to create a strong bond between the metal surface and the paint, improving the adhesion of the topcoat. This is crucial for high-contact surfaces like gear shift knobs, which are frequently touched and can experience wear and tear over time.
To ensure the best results when using an etching primer, it is important to follow these steps:
- Thoroughly clean the aluminum surface to remove any dirt, grease, or oxide coating. This step is crucial as it ensures that the etching primer adheres properly to the metal.
- Immediately apply the etching primer after cleaning. It is important to work quickly and follow the instructions on the primer for the best results.
- Once the etching primer is dry, you can apply your choice of topcoat. Choose a paint that is suitable for metal surfaces and follows the instructions for application and drying time.
- Consider using a clear coat or sealant over the paint to provide extra protection and a smooth finish. This step is optional but can help extend the life of your paint job.
It is important to note that etching primer is not designed to build up, so apply a thin and even coat. If you need to sand out any imperfections, be careful not to expose the metal. If you do expose the metal, you will need to apply more etching primer to those areas before proceeding with the topcoat.

Applying multiple coats
Painting your gear shift knob is a great way to customize your 2008 Chevy Cobalt and keep the red/black color combo going. Here are some detailed instructions on applying multiple coats of paint to achieve a smooth and durable finish:
Preparing the Surface:
Before applying any paint, it is crucial to prepare the surface of the gear shift knob for optimal adhesion. Start by removing the gear shift knob from your Chevy Cobalt by lowering the boot and twisting it down. Use a small flat-headed screwdriver to carefully bend back the pins holding the knob in place, and then gently pull the knob off. Clean the surface of the knob thoroughly to ensure that it is free of any dirt, grease, or residue. You can use a light scuffing technique or an adhesion promoter, such as Dupli-Color Adhesion Promoter, to enhance the adhesion of the paint.
Priming and Base Coat:
Once the surface is prepared, apply a suitable primer, especially if you are working with a metal knob. For aluminum, consider using an etching primer or a zinc chromate primer to prevent paint shedding. If you plan to use enamel or lacquer paint, an adhesion promoter can also help improve adhesion. After applying the primer, choose a base coat color and apply it evenly across the surface of the knob. Let the base coat dry completely before moving on to the next step.
To achieve a rich color and a smooth finish, you will need to apply multiple thin coats of paint. Select the desired color for your gear shift knob and thin the paint slightly if needed to improve its flow. Using a small brush, apply the first thin coat of paint, ensuring that you cover all areas evenly. Allow this coat to dry completely according to the manufacturer's instructions. Once the first coat is dry, inspect the coverage and identify any areas that may require additional attention.
For the second coat, follow the same process, being careful not to overload your brush with paint to avoid drips or an uneven finish. Focus on achieving a consistent and complete coat. If necessary, you can apply a third coat or additional coats, allowing each layer to dry thoroughly before proceeding. Remember that multiple thin coats create a smoother and more durable finish than a single thick coat.
Final Steps:
After applying the desired number of coats and ensuring they are completely dry, gently wipe the gear shift knob with a tissue and some alcohol to remove any excess paint and create a smooth finish, especially around the grooves and crevices. Reattach the gear shift knob to your Chevy Cobalt by lining up the teeth and slots and securing it in place. Allow the paint to cure fully before using the gear shift knob regularly.
By following these detailed instructions for applying multiple coats, you can transform the appearance of your 2008 Chevy Cobalt's gear shift knob with a custom color and a smooth, long-lasting finish.

Drying and clean-up
Before you begin painting, it is crucial to ensure that the gear shift knob is thoroughly cleaned and dried. Use a mild detergent or alcohol to wipe down the surface, removing any dirt, grease, or residue. This step will help the paint adhere better and create a smoother finish. Allow ample time for the knob to dry completely before proceeding.
After cleaning, you may want to consider using an adhesion promoter or primer. While this step is not mandatory, it can significantly improve the adhesion of the paint, especially if the gear shift knob is made of plastic or chrome. Apply the adhesion promoter or primer in thin, even coats, following the manufacturer's instructions. Again, ensure that it is completely dry before moving on to the next step.
Once the gear shift knob is prepared and primed, you can start painting. Choose a suitable paint that is compatible with the material of your knob and the conditions it will be subjected to. Enamel paint is often recommended for its durability and adhesion. Apply thin coats of paint, allowing sufficient drying time between each coat. It is generally better to apply multiple thin coats rather than one thick coat to achieve a smoother and more durable finish.
During the painting process, it is inevitable that some paint may get onto unwanted areas. To clean up these mistakes, use a thin brush or cotton swab dipped in paint thinner or alcohol to gently wipe away the excess paint. Be careful not to smear the paint onto other areas, and always test your cleaning solution on a small, inconspicuous area first to ensure it does not damage the surface.
After you have finished painting and are happy with the results, allow the paint to dry completely. This may take several hours or even days, depending on the type of paint used and the environmental conditions. Refer to the paint manufacturer's instructions for specific drying times and recommendations.
Finally, once the paint is dry to the touch, you may want to consider applying a clear coat or sealant to protect your work. This step is especially important if the gear shift knob will be subject to frequent use and wear. Choose a clear coat that is compatible with your paint type and apply it in thin, even coats, allowing ample drying time.
Remember, always work in a well-ventilated area when painting and using chemicals, and follow all safety instructions on the products you are using. With careful preparation, painting, and clean-up, you can achieve a professional-looking finish on your 2008 Chevy Cobalt gear shift knob.
