Boat polish may seem like a time-consuming process, but it can make a huge difference in the life of your boat. Not only does it make your boat look like it just landed from the shipyard, but it also has implications on the way it runs. A clean boat glides through the water with ease, using less fuel and traveling at faster speeds. Boat polish can also help to protect against the damaging factors your boat comes in contact with on a daily basis. We’ve taken a look at some of the best boat polish options on the market to help you find the one that best fits your needs. Read on to find out how they rate.

_​Benefits of Boat Polish_


Boat polish is one of the top tools to keep in your toolbox. Over time, factors like UV rays, salt water, marine life, and other environmental factors can take a toll on the protective coating of your boat. The coating becomes dull and chalky and will eventually start flaking off your boat, leaving it vulnerable to wear and tear. Boat polish keeps the outer surface shiny, reflecting UV rays and other factors.

Fiberglass boats have a protective layer of resin on the outside. It shields the surface of the boat from cracking and drying out. Boat polish helps to buff away the dry flaky layers and restores the exterior of your boat into its original splendor. This protective layer is known as the gel coat. It protects the colors in your boat’s surface while creating a sheen that looks like new.

Painted boats have a similar exterior shine to protect the painted surface of the boat. Marine paint formulas contain special oils and emollients that create this shine, letting the UV rays and the salt water bounce off.

_​Things to Consider Before You Buy Best Polish for Boat_


  • Type of Boat

The type of boat will greatly influence what type of polish you should purchase for your boat. Fiberglass boats, metal boats and wooden boats are all very different from each other. Each one has different needs to keep it looking its best. Certain boat materials are not compatible with all cleaners and polishes, making it important to know what type of materials are on your boat.

You may even need to invest in multiple formulas to properly clean every aspect of your boat. By choosing the right cleaner you can avoid a cleaning disaster.

  • Environmental Factors and Boat Storage

Where you store your boat has a direct effect on the conditions it faces on a daily basis. Boats that are stored inside and out of the water experience less corrosion and oxidation than boats that live in the water 24/7. These environmental and storage factors should be considered when choosing the best boat polish option for your vessel.

  • The Level of Damage

Choose your polish by assessing the level of damage and imperfections on your boat’s exterior surfaces. Big scratches and dry, flaking paint can benefit from a formula applied by a buffer tool. Smaller scratches can be polished out with a soft cloth and a little elbow grease. Other damages like oxidation, water spots, stains, mineral build-up and more can be solved with a specific formula.

​_Automotive vs. Marine Polish_


While it might be convenient to grab a polish meant for cars to use on your boat, or vice versa, the gel coat on a boat is much different than the clear coat on a car. Polishes are abrasive to help remove the build-up of minerals and grime left on your boat’s hull from the ocean.

The same abrasive formula would scratch the clear coat right off your car, damaging the paint and the surface of your car. There is a reason why two different formulas appear on the market. For best results, stick to the correct formula for your vehicle.

_​How to Polish A Marine Boat_


The first step to polishing is always cleaning the dirt and grime off the surface. If you don’t, you run the risk of more scratches on the finish as you rub in the polish. If you find any mold, you can use a little bit of bleach to remove the bacterial and sanitize the boat’s surface. If the gel coat is greasy, the polish will not stick to the surface.

Use a rag soaked in acetone or another grease remover to prepare the surface for application. Once you have cleaned your boat with a top-quality cleaner, you can proceed to the polishing stage.

Polishing a boat is a large job. It takes time and work to restore the entire thing. It is best to work in small sections, finishing the entire thing before moving on. This allows you to tackle more of the boat in smaller segments, which also means you won’t skip any sections.

Be sure to have the correct tools nearby to complete the job. A pile of microfiber cloths is a great idea to apply and polish the boat. If you plan to use a buffer, have some extra buffing pads available too.

Apply the polish to the surface of your boat, taking care to only put it on safe surfaces. Rub the solution into the boat’s surface and wait for it to dry. Once dry, buff it again with a soft cloth or the buffer to remove the cloudy finish and restore your boat’s protective gel coat. For more tips and tricks, check out this informational video.

Boat Polish Questions

_Frequently Asked Questions_


  • When is a good time to polish my boat?

Answer: Really any time is a great time to polish your boat. But you may want to consider doing it at least at the beginning and the end of each season to keep your boat looking its best.

  • Can I use the same formula on my whole boat?

Answer: It depends on the materials that make up your boat. Some cleaners are more specifically designed than others. If you have a boat with multiple types of materials, it might be best to invest in an all-purpose cleaner that can be used everywhere instead of multiple bottles of specific polish. However, if you have a very specific problem, you might want a more specific cleaner to target the issue.

  • Is wax the same as polish?

Answer: No, wax and polish are two different substances. Polish is abrasive and meant to remove any impurities and imperfections. Wax goes on last as a protective coating. Polishing before application of the wax leaves a surface free and clear of grease, dirt, and other hazards. This leaves room for the wax to properly adhere to the boat’s surface, allowing for the best results.

​_Conclusion_
