Aluminium boats are prone to oxidation, which can cause the metal to lose its shine. To restore an aluminium drift boat, you'll need to strip off any existing coatings, clean the aluminium, and apply a new protective coating. This process can be time-consuming and labour-intensive, but with the right tools and products, it is possible to achieve a professional finish.
What You'll Learn
Stripping and recoating the boat
Stripping and recoating an aluminium boat is a detailed process that requires a lot of elbow grease. Firstly, you need to decide on the method of stripping. Some people use a propane heater to heat up the boat's surface, and then use a scraper to get under the coating. This is a time-consuming method but can be effective. Alternatively, you could use an angle grinder with a wire brush to remove the coating. This method is good for removing stubborn areas and corrosion. It is important to wear protective gear, such as heavy gloves, and work in a well-ventilated area when using an angle grinder.
Once the majority of the coating has been removed, you can use a sander to smooth out the surface and remove any remaining residue. This will ensure that the new coating will adhere properly. It is important to use the correct grit sandpaper for the job; too fine, and it won't be effective, too coarse, and it may damage the aluminium. A medium grit, such as 36-grit, is a good starting point.
After sanding, the aluminium will need to be cleaned with a dedicated aluminium cleaner to remove any grease, dirt or oxidation. Ordinary soap and water will not effectively clean aluminium, so it is important to use the correct products. Once the boat is clean, it should be dried thoroughly and any remaining residue removed.
Now the boat is ready for the new coating. There are many products on the market, such as Coat-it, Glovit, Gluvit, Line-X, and UHMW. Each product has its own advantages and disadvantages, so it is important to research which one is best suited to your needs. Some products are smoother, some are thicker, and some are more resistant to UV light. The application method will also vary depending on the product, so be sure to read the instructions carefully. Some products require a roller for application, while others can be sprayed on.
Finally, it is important to allow the new coating to cure properly before using the boat. This may take several hours or even days, depending on the product and the temperature.

Removing algae, barnacles and zebra mussels
Removing algae, barnacles, and zebra mussels from your aluminium drift boat is a simple process with the right product. Aurora Marine's Algex is a no-fume formula that comes in a ready-to-use spray bottle. Spray it directly onto the algae, and it will penetrate and break the bond between the algae and the aluminium, making it easy to remove. For best results, scrub the affected areas with a brush and then rinse with a pressure washer or a garden hose. Alternatively, you can use a scraper to remove the softened barnacles and zebra mussels.
Algex is safe to use on aluminium and will not pit the metal or strip paint. It is also effective at removing rust and oxidation and can be used on aluminium boat bottoms, pontoons, outboards, sterndrives, and propellers.
If you are looking for a more heavy-duty solution, Aqua-Chem is another product that claims to remove zebra mussels, barnacles, and algae from all types of boat hulls and bottoms, including aluminium. Aqua-Chem contains inhibited and enhanced hydrochloric acid and is safe for the environment. However, it is important to follow the safety warnings and use goggles and rubber gloves when handling this product.
For a more natural approach, you can try using a propane heater to heat the affected areas and a scraper to remove the buildup. This method may require more elbow grease but can be effective in removing stubborn growths.
Remember to always follow the manufacturer's instructions and take the necessary safety precautions when using any cleaning products.

Cleaning and brightening exposed metal surfaces
To restore an aluminium drift boat, it is important to clean and brighten exposed metal surfaces. This can be done using a dedicated aluminium boat cleaner, such as Aurora Alumabrite CBX, which is a concentrate that needs to be cut with water in a 1:12 ratio. It can be applied with a garden sprayer, but it is recommended to invert the boat to avoid getting overspray on the inside. Alternatively, you can use a product like Arcair - Protex, Alclean aluminium cleaner, which is available at welding shops. It is important to wear gloves and work outdoors or in a well-ventilated area when using these products, as the fumes can be dangerous. After cleaning, the surface can be polished with a product like Aurora Boat Scrub to achieve an even brighter finish.
Before applying any cleaner, it is important to remove any debris, dust, or grease that may have built up on the boat. This can be done by using a pressure washer to clean the boat inside and out, paying close attention to the seams to check for leaks. If there are any exposed fiberglass areas, they should be reinforced with epoxy and sanded before painting. It is also recommended to cover any painted areas of the boat to protect them from the cleaner, as it may damage the paint.
Once the cleaning and brightening process is complete, the topsides of the boat can be protected with a product like Premium Boat Shine, and the bottom can be coated with a product like VS721 Bottom Coat to maintain the shiny finish.

Repairing the interior of the boat
Repairing the interior of an aluminium drift boat is no small task and requires a lot of elbow grease. Here is a step-by-step guide to help you through the process:
Step 1: Stripping
First, you need to strip the interior of the boat down to the original surface. This can be done using a propane heater to heat the existing coating and a scraper to remove it. An angle grinder with a wire brush can also be used to remove any stubborn areas and to clean the entire surface. It is important to wear heavy gloves and work in a well-ventilated area when undertaking this step.
Step 2: Cleaning
Once the interior is stripped, it is crucial to clean the aluminium surface to remove any remaining residue. A dedicated aluminium boat cleaner or a phosphoric acid-based product can be used for this step, ensuring that you follow the manufacturer's instructions. Be cautious when working with chemicals and wear appropriate protective gear.
Step 3: Prepping the Surface
Before applying any new coatings or paint, it is essential to prepare the surface properly to ensure a strong bond. This involves sanding the aluminium to create a rough surface for the new material to adhere to. Use sandpaper or a sanding disk with a suitable grit size, such as 60-grit or 36-grit, to thoroughly sand the interior. Vacuum and wipe down the surfaces to remove any dust or debris.
Step 4: Repairing Structural Damage
If there is any structural damage, such as holes or cracks, these need to be addressed before proceeding. Use a suitable filler or epoxy to repair the damage and ensure it is sanded smooth once cured.
