Boat Waxing: Best Practices For A Gleaming Finish

Waxing a boat is a great way to keep it looking its best, but it's not a simple process. A proper waxing not only keeps a boat looking sharp but also helps prevent dirt and grime from permanently marking or staining its surfaces. In this article, we'll outline the steps to waxing a boat, recommend the best tools for the job, and explain why waxing is important.

Characteristics of the Best Way to Wax a Boat

Cleaning your boat before waxing

To ensure the best results when waxing your boat, it is important to clean your boat thoroughly beforehand. Here is a step-by-step guide to cleaning your boat before waxing:

Park your boat securely

First, park your boat on a flat, even surface, preferably in a place where you would normally wash your car. Secure your boat to the trailer to prevent any unexpected movement. If you are planning to use a power buffer, it is best to detach the trailer from your car.

Hose down the exterior

Use a hose to spray the exterior of the boat with plain water, starting from the top and working your way down. This will help to loosen and remove any loose dirt, grime, algae buildup, or other gunk, especially if the boat has been sitting in the water.

Scrub gently with a sponge

Use a clean, wet sponge to gently scrub the exterior of the boat. Start with plain water and then, if needed, move on to a mild detergent or a special boat soap. Be sure to choose a non-abrasive cleaner if your boat is new or has a fibreglass finish.

Remove stubborn spots

For more serious spots of buildup, you can use fine-grain 220 sandpaper to clean them off. Be careful not to use too much pressure, as you could damage the finish. Do not use a power washer, as this can also damage the finish and affect the efficacy of the gel coat.

Rinse and dry

Once you have finished scrubbing, be sure to rinse the boat thoroughly with clean water and allow it to dry completely before moving on to waxing. You can use a squeegee to speed up the drying process if needed.

Remove old wax

Use rags soaked with toluene or another dewaxing solvent to remove any traces of old wax. Sweep the rag in one direction, applying light pressure. Allow the solvent to evaporate completely before moving on to waxing.

Choose the right wax

Different types of boats require different kinds of wax. For example, if you have a painted aluminium boat, you will need to choose a wax that will not damage the paint or any vinyl trim. If you are unsure, it is best to consult a professional or refer to the manufacturer's instructions for your boat.

By following these steps, you will ensure that your boat is clean and ready for waxing, which will help you achieve the best possible results and a finish you can be proud of!

Choosing the right boat wax

The type of wax you use on your boat depends on several factors, including the style and surface of the boat's gel coat, and whether you want to use a power buffer or not.

Style and surface of the boat

The variety of boating wax you use depends on the style and surface of your boat's gel coat. Collinite 885 is a commonly used and recommended wax for boats. It is also used in surfing and for other purposes.

Power buffer or not?

If you want to use a power buffer, you will need to choose between a rotating buffer and an orbital buffer. A rotating buffer spins in circles at high revolutions and is suitable for experienced users. An orbital buffer vibrates back and forth and is safer to use, but it is only good for applying a thin layer of wax.

If you don't want to use a power buffer, you can save money and use elbow grease to buff the wax by hand. This method is more labour-intensive, especially for larger boats, but it can save you money on renting or buying a power buffer. It also reduces the risk of damaging the fiberglass.

Combination of products

You can use a combination of products to clean, buff, and wax your boat. First, use a compound to buff the gel coat and rid it of chalky oxidation and other markings. Then, apply a wax to protect the hull and make it shine. Alternatively, you can use a multipurpose cleaner wax, but these are generally not as effective.

Frequency of waxing

Most boaters only wax their entire boat at the beginning and/or end of the season. However, some heavy users may choose to do an additional interior or above-waterline wax every month or two.

Using a power buffer

For the at-home DIY enthusiast, a dual-action boat polisher is recommended. This type of polisher both oscillates and rotates, making it safer and easier to operate. It is much lighter and less likely to damage graphics or protruding hardware. Dedicated dual-action polishers, such as the Meguiar's Professional DA MT300, offer more power and larger pad sizes.

When using a power buffer, start at the slowest speed. Touch the pad lightly to the surface before starting the buffer to avoid spraying the product everywhere. Apply a dime-sized amount of product to the pad and place it firmly against the hull. Work in overlapping 3-by-3-foot sections, turning the buffer off before moving to the next area. Wipe the area clean with a microfiber towel.

If you are experienced, you can also use a rotating buffer, which spins in circles at high revolutions and produces a lot of power. However, caution is advised as it can easily damage your hull if not used correctly. An orbital buffer is a safer alternative for applying a thin layer of wax, as it only vibrates back and forth.

Waxing the bottom of the boat

There is a debate in the boating community about whether to wax the bottom of a boat. Some people claim that waxing the bottom of a boat causes it to stick tighter to the water, leading to a slight loss of speed or efficiency. On the other hand, others argue that a waxed hull is less likely to be stained by murky water and mud, and that the long-term aesthetic improvement and protective barrier are worth any potential speed loss. Ultimately, the decision to wax the bottom of your boat is up to you, but it's important to consider the benefits and drawbacks of each option.

If you decide to wax the bottom of your boat, there are several steps you should follow to ensure a successful outcome. Here is a detailed guide to help you through the process:

• Prepare the Boat's Surface: Park your boat on a flat, even surface, securing it on a trailer. Remove all loose dirt, grime, algae buildup, and other gunk, especially if the boat has been sitting in the water. Use a hose or a gentle spray to rinse the exterior with plain water, and then use a clean, wet sponge to start scrubbing gently. For serious spots of buildup, you can use fine-grain 220 sandpaper.
• Clean the Old Wax: Use rags soaked with toluene or another dewaxing solvent to remove any traces of old wax. Sweep the rag in one direction with light pressure. Allow the solvent to evaporate before proceeding to the next step.
• Wash with Detergent: Finish washing the surface using a sponge and a special boat soap or a mild solution of dishwashing detergent and warm water. If there are stains, you can use a small amount of bleach to disinfect and clean thoroughly. Rinse the boat thoroughly and ensure it is completely dry before moving on.
• Choose the Right Wax: Select a wax specifically formulated for boats, such as Collinite 885, PolyShine, or LifeWax. Avoid using automotive wax, as it is not intended for the marine environment.
• Apply the Wax: Use an application pad or extra-soft rag to rub on the wax in small, circular motions. Focus on one section at a time, following the manufacturer's recommendations. You might need to buff each small area before moving on. Cover one side of the boat at a time for the best results.
• Buff the Wax: Use an extra-soft towel or a chamois to buff the wax, removing all excess wax and polishing until you achieve a mirror finish. Repeat this process until you've covered every surface. You can also use a power buffer for this step, but be cautious as it can damage the finish if not used properly.

Remember to always work in a well-ventilated area and wear protective gear, such as gloves, eye coverings, and a mask or ventilator, when waxing the bottom of your boat.

Waxing by hand

Waxing a boat by hand is a time-consuming process but can be done with a few simple tools. First, ensure your boat is out of the water and parked on a flat surface. Spray the boat down with water to remove any loose dirt and grime. Use a sponge and a mild detergent or boat soap to scrub the boat and remove any remaining dirt. If there are stubborn spots, use fine-grain sandpaper to clean them off. Rinse the boat again and allow it to dry completely.

Next, choose an appropriate boat wax. Some popular options include Collinite 885, PolyShine, and LifeWax. Apply the wax to a soft cloth or foam buffing pad. Start at the transom and work towards the bow in small sections. Use a circular motion to apply the wax to the boat, being careful around fittings and in tight spaces.

Allow the wax to dry for 5-10 minutes. It will start to look hazy when it is ready for buffing. Use a soft towel or terry cloth to buff the wax in a circular motion until you achieve a shiny, mirror-like finish. Repeat this process until you have covered the entire boat.

For a quick touch-up between full waxes, you can use a spray-on wax. Simply spray it on and wipe it down to maintain the shine.
