There are several types of pads that can be used for compounding a boat, including foam, wool, and microfiber. Foam pads are typically used for painted surfaces, such as cars and boats, as they can withstand higher temperatures. Wool pads, on the other hand, are preferred for gel-coated surfaces as they don't generate high temperatures that could damage the gelcoat. Wool pads are also effective at cutting through oxidation and are safer to use on heat-sensitive parts of a boat. Microfiber pads are a newer option that can be used for both cutting and polishing, but they may require an additional step with a foam pad to achieve a flawless finish. When choosing a pad, it's important to match the aggressiveness of the compound or polish with the pad to ensure efficiency and avoid damage to the boat's surface.

Wool pads are best for compounding gel-coated surfaces like boats
Wool pads are the best choice for compounding gel-coated surfaces like boats. This is because wool is highly effective at removing extreme swirls or oxidation on very hard paint, and it does so without generating high temperatures that could damage the gel coat.
Wool pads are highly aggressive and are used for cutting or heavy compounding. They are ideal for tackling very dull, oxidised surfaces. If you haven't detailed your boat in many years, or if it has been exposed to a lot of UV light and harsh environmental conditions, a wool pad is the best option.
Before final polishing, an oxidised gel coat needs a rigorous amount of cutting (also known as rubbing or compounding). In severe cases, you may need to start by carefully wet sanding the surface, followed by using a wool buffing pad and a marine-grade cutting compound to expose the gel coat underneath the oxidation layer.
Wool pads are also safer to use on heat-sensitive parts of your boat, such as bumpers and spoilers. This is because wool generates less heat, resulting in a cooler surface. However, wool does require a bit more skill and caution as it can leave buffer trails if not used correctly.
For final polishing, a foam pad is the better choice. Once you've cut back the gel coat, use a foam pad to apply a polishing compound, followed by a wax coating to finish. Foam pads are also a good option if there is only a subtle amount of oxidation. They are also easier to clean than wool pads and are more comfortable to hold for hand buffing.

Foam pads are used for compounding painted surfaces
Foam pads are ideal for compounding painted surfaces, such as cars and boats. They are constructed of stiff, coarse foam that can withstand high temperatures, making them suitable for use on painted surfaces. Foam pads are designed to be attached to a backing plate, which is then connected to a polisher or buffer machine.
When compounding a painted surface, it is important to start with a properly prepared surface. This involves removing any large scuffs or scratches by sanding with increasingly finer abrasive discs or papers, typically down to 1200 grit or finer. Once the surface is adequately prepared, you can proceed to use the foam compounding pad.
Foam compounding pads are used in conjunction with liquid rubbing compounds that contain fine abrasive particles. The pad itself also contributes to the abrasive action, refining very tiny scratches left by the previous sanding process. It is important to note that foam pads can generate significant heat, so caution must be exercised to prevent overheating.
When using a foam compounding pad, follow the manufacturer's instructions and safety guidelines. Wear appropriate protective gear, including gloves and eye protection, and work in a well-ventilated area. Additionally, it is recommended to test the foam pad on a small, inconspicuous area first to ensure it does not cause any damage to the painted surface.
Foam compounding pads come in various sizes, such as 3M's 4-inch, 6-inch, and 8-inch options. Selecting the appropriate size depends on the area you need to cover and the level of detail required. Smaller pads are ideal for spot buffing and reaching tight spaces, while larger pads provide maximum coverage and efficiency for larger surfaces.

Buffing pads are also used to apply wax, sealants and other coatings
Buffing pads are used to apply liquid abrasive compounds and polishes to a fibreglass, painted, or metal surface to give them a shine. They are used in place of doing the work by hand, saving time for busy boaters.
Buffing pads are also used to apply wax, sealants, and other coatings. After the surface has been prepped for final compounding and/or waxing, you are ready to use your buffing pad. Foam pads come in different degrees of aggressiveness. 3M's white foam pads are suitable for compounding, their black pads for polishing, and their light blue pads for ultra-fine polishing or applying wax. Foam pads are more forgiving for beginners but can get very hot, so use caution when working with gelcoat.
Finishing pads are often used for the last step of a detailing job, making them perfect for applying a sealant or wax to lock in the freshly finished shine. These pads will help bring out the "just-detailed" boat glow that makes boaters gleam with pride.
Microfiber pads are relatively new in the detailing world, but they can be used for compounding and polishing too. They are usually more abrasive than foam pads and will need to be followed up by a foam pad to get the proper finish on a detailing job.
Wool pads, similar to foam pads, offer a range of uses depending on their design. You can find aggressive, compounding wool pads or milder finishing wool pads. Even if you use a wool pad for finishing, you may need to supplement with a foam pad at the very end because wool is an abrasive material.
Buffing pads provide a more efficient means of working wax into your boat's finish. Pads hold wax much more evenly than a towel and are easy to attach to a machine, allowing for a more even and consistent material removal.

Buffing pads are attached to polishers by a backing plate
Buffing pads are essential for restoring the lustre of a clear coat or any glossy surface. They are also referred to as polishing pads and are used to polish paint and other hard materials. They can also be used to apply wax, sealants and other coatings.
Buffing pads are attached to polishers by what is called a backing plate. This is a plastic or rubber disc that has a threaded arbor on one side and a hook and loop (Velcro) face on the other side. The threaded arbor is used to screw the backing plate into the polisher's spindle, while the hook and loop face is used to stick the buffing pad onto the backing plate.
The type of threaded arbor depends on the type of polisher being used. Dual Action (DA) Orbital Polishers use a backing plate with a male threaded arbor, while Rotary Polishers use a female threaded arbor.
When choosing a buffing pad, it is important to consider the material, flexibility, cut, surface paint, surface size and compatibility with your buffing machine. Buffing pads are typically made of wool, acrylic fibres or foam, with each material offering different levels of abrasiveness and heat generation. For example, wool pads are highly aggressive and effective at removing heavy oxidation, but they require skill to use as they can leave buffer trails if not used properly. On the other hand, foam pads come in different degrees of aggressiveness, with white foam pads suitable for compounding and black pads for polishing.
The flexibility of the buffing pad is important depending on the curves and edges of the surface being polished. A flat surface can use a rigid pad, but a car or boat surface requires a pad with flexibility. The cut of the pad refers to how it removes defects, with aggressive pads being able to remove deep scratches and imperfections quickly, while less aggressive pads require more buffing time and leave a smoother finish.
When it comes to surface paint, different buffing pads are recommended for clear coats, dark paint and other types of paint. The size of the buffing pad should also be considered, with larger pads providing more buffing coverage and efficiency, while smaller pads are better for hard-to-reach areas. Finally, if you are using a power tool for buffing, ensure that the buffing pad is compatible and comes with a backing plate to attach it securely to the polisher.

Buffing pads are divided into two types: compounding and polishing
Buffing pads are used to apply liquid abrasive compounds and polishes to a fibreglass, painted, or metal surface to give them a shine. They are used in place of doing the work by hand, saving time for busy boaters.
Buffing pads should be used after the surface has been prepped for final compounding and/or waxing – which means removing any big scuffs or scratches by sequentially sanding with finer and finer abrasive discs or papers. Once you have reached this point, you are ready to use your buffing pad.
Buffing pads can be broadly divided into two types – compounding and polishing. Each of these types can be made from either fibre or foam. Compounding pads are used with liquid rubbing compounds that contain fine abrasive particles. Foam compounding pads are constructed of stiffer, coarser foams than those used for polishing, and they can generate a lot of heat. Foam is typically used on painted surfaces (like cars and painted boats) that can tolerate the higher temperatures. Wool compounding pads are preferred for use on gel-coated surfaces (like boats), since they don't generate high surface temperatures that can damage a gelcoat surface. Wool pads also work well on painted surfaces.
Polishing pads are used with liquid polishes and glazes (super-fine polishes) containing even finer abrasives than those in compounds, and continue the scratch refining process to the point where the scratches are no longer visible and the surface has a glossy shine. Polishing pads are constructed of softer foam or softer, thinner fibres that are typically acrylic, or acrylic/wool blends. The yarns usually have less “twist” than those used in compounding pads, making them softer and less aggressive.
Pure wool pads tend to be more abrasive and are most often used for compounding. Wool is a little more challenging to use for a beginner since too much pressure can cut the surface too quickly or cause swirl marks if you're not careful. But it doesn't get as hot as foam, so that can be a plus if you are working on gelcoat. Acrylic/wool blends have finer, softer fibres, and are usually used for polishing.
Foam pads come in different degrees of aggressiveness. 3M's white foam pads are suitable for compounding, their black pads for polishing, and their light blue pads for ultra-fine polishing or applying wax. Foam pads will often have a convoluted face designed to better hold compounds and polishes so as to reduce the slinging of the liquid off the pad during use. Foam pads tend to be a little more forgiving for beginners, but can get very hot – so use with caution when working with gelcoat.
