Best Polishes For Aluminum Boats: Shine And Protection

Aluminium boats are durable and can withstand polishing easily. Before polishing, it is important to clean the boat thoroughly, removing debris, dust, and even old paint. There are several products available for polishing aluminium boats, including Mothers Polishing Compound, Jewelers Rouge, Heavy Metal Green, Flitz, and dedicated polishes like Autosol and Marine Aluminium Polish. Power buffers can be used to speed up the process, but they can be loud and labour-intensive. After polishing, it is recommended to protect the surface with a coating such as Sharkhide or Vinyl Wrap to prevent oxidation and corrosion.

The importance of cleaning your boat before polishing

Polishing an aluminium boat is a multi-step process that requires thorough preparation. One of the most important steps is cleaning the boat before polishing it. This step is crucial because it ensures that the polishing process is effective and long-lasting. Here are some reasons why cleaning your boat before polishing is essential:

Removes Dirt, Debris, and Oxidation:

Over time, boats are exposed to various elements, including saltwater, UV rays, and environmental pollutants. These factors can lead to the build-up of dirt, grime, and oxidation on the boat's surface. By cleaning the boat thoroughly before polishing, you ensure that these contaminants are removed. This step is critical because applying polish directly over dirt or oxidation will not yield desirable results. The polish may not adhere properly, and the final finish will be uneven and lacklustre.

Ensures Better Adhesion and Longevity:

A clean surface is essential for the polish to adhere properly. When you polish an aluminium boat, you are essentially filling in microscopic scratches and creating a protective layer. If the surface is not clean, the polish may not bond correctly with the aluminium, resulting in a less durable finish. Proper cleaning ensures that the polish adheres optimally, enhancing its longevity and protective properties.

Restores and Enhances Appearance:

Cleaning the boat before polishing is a vital step in restoring and enhancing the boat's appearance. Polishing alone will not remove stubborn stains, discolouration, or marks. By cleaning the boat first, you can address specific issues such as waterline stains, rust, or exhaust stains. This step ensures that the boat's surface is free from any impurities, allowing the polish to create a uniform and brilliant shine.

Facilitates Inspection and Maintenance:

Cleaning your boat before polishing provides an opportunity for a thorough inspection. As you clean, you can identify areas that require extra attention, such as scratches, nicks, or areas of oxidation. This allows you to focus your polishing efforts on these specific spots, ensuring that the final finish is consistent and flawless. Additionally, cleaning helps you maintain the boat's overall hygiene, which is essential for the health and longevity of the vessel.

Prepares the Surface for Optimal Results:

The goal of polishing an aluminium boat is not just to make it look good but also to protect it from the elements. By cleaning the boat first, you prepare the surface to receive the polish optimally. This includes removing old paint, ensuring the surface is dry, and using the appropriate cleaning solutions. A well-prepared surface will yield better results, and the polish will create a more durable and glossy finish.

In summary, cleaning your boat before polishing is a critical step in the overall process of maintaining and enhancing your aluminium boat. It ensures that the polishing process is effective, long-lasting, and aesthetically pleasing. By taking the time to clean your boat thoroughly, you set the foundation for a high-quality finish that will protect your boat and keep it looking its best for years to come.

The best products to clean an aluminium boat

Cleaning and polishing an aluminium boat can be a lot of work, but the results are rewarding. Here is a guide to the best products to use to clean an aluminium boat.

Cleaners

First, you need to clean your boat thoroughly. A product such as Kwik Shine is ideal for cleaning and protecting a painted aluminium boat. It is safe to use on paint as it does not contain wax, which can cause paint to bubble. Kwik Shine is also an excellent cleaner, removing bird droppings, bug splatter, fish blood, grease, oil, and grime without harming the paint.

For bare aluminium surfaces, you can use a product such as Better Boat's Marine Aluminium Polish, which is designed for use on aluminium surfaces such as pontoons, jon boats, and canoes. It delivers a long-lasting, gleaming finish and offers UV protection and stain resistance.

Polishes

Once your boat is clean and dry, you can move on to polishing. A mild buffing compound can be used to remove hard stains. You can also use a metal polish like Flitz, but if you use a polish, you must then protect the surface with another product.

Mothers Polishing Compound is a popular choice for polishing aluminium boats, but it requires a lot of elbow grease. You can also try Jeweler's Rouge or Autosol Aluminium Polish, which can be applied by hand or with an electric/air polisher.

Protectants

After polishing, you will need to protect the surface. Sharkhide is a popular product to protect aluminium after polishing. Vinyl wrap is another option to protect the surface and prevent porosity (aluminium rust).

Buffing

You can buff your aluminium boat by hand, but this is very labour-intensive. A power buffer is recommended to make quick work of the job. Be sure to apply your chosen polish consistently, neither over-working nor under-working any area.

Other tips

Before polishing, some boat owners will strip off old paint if they are completely restoring their boat. You can also use a low-micron cleaner and an anti-oxidant to treat old and worn-out aluminium and restore it as best as possible.

The benefits of using a power buffer

Using a power buffer to polish your aluminium boat can offer several advantages over hand-buffing. Firstly, it saves time and effort, especially for medium to large boats. While hand-buffing can be labour-intensive and time-consuming, a power buffer can quickly cover larger surface areas, making it more efficient and convenient.

Secondly, power buffers provide a more consistent finish. They ensure an even application of the polish, resulting in a uniform shine across the boat's aluminium surface. This consistency is challenging to achieve with hand-buffing, where it is easier to overwork or underwork certain areas.

Additionally, power buffers can be useful for removing tough stains, scratches, and oxidation. They are designed to handle aggressive compounding, making them ideal for restoring aluminium boats to their former glory. By using a power buffer, you can achieve a deeper level of cleaning and restoration, removing fine scratches and surface-level oxidation that may be difficult to tackle by hand.

Another benefit of power buffers is their versatility. They can be used with various polishes and compounds specifically designed for aluminium boats, allowing you to choose the best product for your boat's needs. Power buffers are also suitable for both casual boat owners and experienced detailers, as they offer adjustable settings to cater to different levels of expertise.

Finally, power buffers can enhance the overall appearance and longevity of your boat. By effectively removing stains and oxidation, power buffers can restore the shine and protect the integrity of the aluminium surface. This not only makes your boat look aesthetically pleasing but also helps maintain its value over time.

The importance of protecting your aluminium boat after polishing

Polishing an aluminium boat is a great way to restore its shine and improve its overall appearance. However, it is important to remember that this process also removes the natural protective layer of oxidation on the aluminium surface, leaving it vulnerable to further damage. Therefore, taking steps to protect your boat after polishing is crucial to maintaining its condition and ensuring the longevity of your vessel.

Preventing Oxidation

One of the main challenges aluminium boat owners face is the issue of oxidation. Over time, aluminium naturally develops a layer of oxidation, a dull-looking protective coating that shields the metal from further corrosion. When you polish your boat, you remove this protective layer, leaving the aluminium exposed. To prevent rapid re-oxidation and the formation of unsightly stains, it is essential to apply a protective coating after polishing.

Maintaining Shine and Appearance

Polishing your aluminium boat can give it a stunning mirror-like finish. However, without proper protection, this shine can quickly fade. Applying a protective coating helps preserve the boat's shine by creating a barrier that repels dirt, grime, and other contaminants. This not only keeps your boat looking its best but also reduces the frequency of polishing and maintenance, saving you time and effort in the long run.

Protecting Against Stains and Corrosion

Aluminium is susceptible to staining and corrosion, especially when exposed to saltwater, bird droppings, bug splatter, and other environmental factors. By applying a protective coating, you create a barrier that resists staining and corrosion, keeping your boat in optimal condition. This is particularly important for boats used in saltwater environments, as saltwater can accelerate corrosion and damage the aluminium surface.

Extending the Lifespan of Your Boat

Proper protection after polishing is key to extending the lifespan of your aluminium boat. By inhibiting oxidation, preventing stains, and reducing corrosion, you can maintain the structural integrity of your vessel. This means you'll spend less time and money on repairs and maintenance, allowing you to enjoy your boat for many years to come.

Choosing the Right Protection

There are various products available to protect your aluminium boat after polishing. Some polishes, such as the one offered by Better Boat, are engineered with advanced polymers to provide both a brilliant shine and essential UV protection. Others, like Sharkhide and Vinyl Guard, are specifically designed to protect against staining and corrosion. When choosing a protective product, consider your boat's specific needs and the type of environment it is exposed to.
