Buffing is a great way to restore the shine to a car's paintwork. Over time, paint can become dull and faded due to oxidation, contamination, and scratches. To remedy this, you can use foam or wool pads to buff the paint and restore its smoothness and shine. Foam and wool pads have different properties and are suitable for different levels of oxidation and scratches. Wool pads are traditionally used for deep scratches and heavy oxidation, while foam pads are more forgiving and suitable for polishing and finishing. In this article, we will explore the pros and cons of using foam or wool pads for buffing oxidized paint and provide a step-by-step guide on how to effectively buff and restore paintwork.
What to buff paint oxidation with: foam or wool?
| Characteristics | Values |
|---|---|
| When to use wool | Wool pads are for deep scratches and primarily for oxidation. If the paint is heavily oxidized, use a wool pad with a solid compound. |
| When to use foam | Foam pads are used after using wool to shine with a polish and then a wax application. Foam pads are more forgiving and don't gunk up as much. |
| Other tools | Sandpaper, electric buffer, cutting compound, polishing pads, wax or other finishing product, microfibre cloth |

What You'll Learn
Wool pads are for deep scratches and oxidation
Wool pads are primarily used for addressing deep scratches and oxidation on paint. They are ideal for cutting and enhancing detailing finishes. Wool pads are crafted from premium sheep's wool, which provides maximum cutting efficiency. The short bristles deliver enhanced abrasion for improved paint correction results.
Wool pads are perfect for removing deep scratches and oxidation from paintwork. The coarse structure of the woolpad's fibres gives it an abrasive quality, making it effective for cutting through and removing deep scratches.
Wool pads are also suitable for use on gel coats, very soft lacquers, and sticky paint. They generate less heat than other pads, reducing the risk of paint burn during intensive polishing. However, wool pads are not ideal for finishing work due to the small scratches the wool fibres can leave behind. For this step, it is recommended to switch to foam or microfiber pads.
When using wool pads, it is important to ensure they are properly maintained and cleaned to extend their effectiveness and longevity. Compressed air can be used to clean the pads and ensure they are free of any debris before use.
Overall, wool pads are a great option for addressing deep scratches and oxidation on paintwork, but they should be complemented with foam or microfiber pads to achieve the best final finish.

Foam pads are more forgiving and don't gunk up as much
Buffing is the process of making the surface of your car's paint smooth and shiny by rubbing it. It can be done by hand or with a machine. When done correctly, it can make your car look brand new again. However, if done incorrectly, it can destroy the paint and damage the body of the car.
Foam and wool pads are commonly used for buffing. Wool pads are primarily used for deep scratches and oxidation. If the paint is heavily oxidized, a solid compound and wool pad are necessary. Foam pads, on the other hand, are more forgiving. They are used after the initial buffing with a wool pad to shine the surface with polish and then a wax application.
Foam pads have the advantage of not gunking up as much as wool pads. This means that they require less frequent cleaning during the buffing process. While foam pads may clog quickly when used on large surfaces like boats, they are still preferred for their smoother finish.
It is recommended to start with the least abrasive combination when buffing and work your way up if needed. This helps avoid causing more harm than good to the paint surface. Foam pads are generally gentler than wool pads and are used for less severe oxidation.
In summary, foam pads are preferred for their forgiving nature and reduced gunking. They are ideal for polishing and finishing, providing a smooth surface for the final wax application. However, for heavily oxidized surfaces, a wool pad is still necessary for the initial buffing process.

Sandpaper can be used to level the surface before buffing
Sandpaper can be used to level the surface of a car before buffing. This process is known as sanding and is an important step in preparing the car's surface for a new coat of paint. It helps to remove imperfections, scratches, and old paint, creating a smooth and even surface for the new paint to adhere to.
The key to successful sanding is selecting the appropriate grit size for the sandpaper. Grit size refers to the number and density of abrasive particles on the sandpaper, and different grit sizes are suited to different tasks. Lower grit sizes, such as 24 to 40, are used for heavy paint removal and shaping body fillers. For light paint removal and polishing metal before priming, you would use a grit size between 80 and 150.
When preparing a car's surface for buffing and a new coat of paint, it is generally recommended to start with a lower grit size to remove any old paint or imperfections, and then move to a higher grit size to smooth out the surface. For example, you might start with 180-grit sandpaper to remove rust or surface damage, and then switch to 320-grit paper to remove the scratches left by the coarser sandpaper. Finally, you would use a very fine grit size, such as 600-grit, to sand the paint and prepare the surface for the new coat.
In some cases, even finer grit sizes may be required to achieve an ultra-smooth finish. Sandpaper discs in the 1,500 to 4,000 range are ideal for colour sanding and buffing, ensuring that the surface is perfectly smooth and level before applying a rubbing compound.
By using sandpaper to level the surface before buffing, you can achieve a smoother and more consistent finish for your new coat of paint.

Buffing can be done by hand or with a machine
Buffing is a process that can restore the shine to dull and faded paintwork on cars. It involves making the surface of the paint smooth and shiny by rubbing it, either by hand or with a machine. When done correctly, buffing can make a car look like new, but if done incorrectly, it can destroy the paint and damage the body of the car.
Buffing can be aggressive or gentle. Aggressive buffing may be necessary to remove deep scratches and oxidation. Wool pads are typically used for aggressive buffing, as they are more abrasive. Foam pads, on the other hand, are used for gentle buffing and finishing. They are less likely to clog and are more forgiving, but they may not be suitable for heavily oxidized surfaces.
When buffing by hand, it is important to start with the least abrasive combination and work your way up to more aggressive combinations if needed. This will help to avoid causing more harm than good. It is also important to keep the work area clean and to remove any contaminants before buffing to avoid scratching the paint.
After buffing, the surface should be polished to a high-gloss finish using a dedicated polish and polishing pad. A protective coating should then be applied to prevent oxidation and maintain the shine.

A protective coating should be applied after buffing
Buffing is an effective way to restore shine to oxidised paint. However, it is important to protect the paint after buffing to maintain its appearance and prevent further oxidation.
One way to protect the paint is to apply a sealant or wax coating. Sealants and waxes act as a protective barrier, shielding the paint from the sun's UV rays and environmental contaminants. They can add years of protection and help to maintain the shine and depth of colour of the paint. Klasse High Gloss Sealant Glaze is a recommended product that uses an acrylic formula, providing deeper shine and better protection compared to petroleum-based car wax products.
Another option for protection is to use a ceramic coating. Ceramic coatings offer a moisture-rich, protective barrier that can help restore and maintain the appearance of the paint. Armor Shield IX is a popular choice for a DIY nano ceramic coating.
Additionally, wrapping the vehicle can also provide protection from oxidation. However, this method may be more suitable for those who do not intend to use or showcase the paint layer, as it would require rewrapping when the colour becomes boring.
Applying a protective coating after buffing is essential to preserve the paint's finish and prevent future damage. By taking the time to properly maintain and care for the paint surface, you can ensure that your vehicle maintains its shine and aesthetic appeal.
