What Is a Boat Polish?

Best Boat PolishPolishing is not actually coating the boat, as it is popularly believed. In reality, the pitted surface is removed. Both compounds of polish and buffing are abrasives. By removing imperfections, discoloration, and scrapes from the surface, they restore the shine of the fiberglass gel coat of the boat, enhancing the body shine and its original lively look.

This high gloss of the paint of the sailboat is maintained by pure polish overcoated with wax. If you are asking yourself, “Why polishing your boat is important?” we have the answer you are searching for!

The boat polish is a synthetic mix that is very similar to wax. It is mostly used on new boats or after the oxidation has been removed from older ones. The polish blocks UV light prevents damages caused by it and makes the surface of the vessel non-stick. Everybody needs their boat to look extraordinary, and using a boat polish will take it back to how it was when you first bought it.

However, polishing also involves protecting your boat from the elements. Stains, corrosion, and oxidation can build up, which can become a much bigger problem. These issues need to be treated accordingly.

If your gel coat is in good condition, you would want to spend time keeping it in the same state all through the season. Maintenance of essential gel coat starts with waxing and/or polishing. What is the difference between polish and wax? All quality boat waxes are designed to protect and seal the gel coat with a coating that repels the sun’s harmful rays, water, dirt, salt and. Polishes, on the other hand, usually contain a cutting agent to remove the gel coat’s oxidation and shine.

Due to the intense sun and the impact of UV rays, the paint of the hull begins to matt over time. If you want your yacht always to look new, it is advisable that you polish it once a year. This creates a UV filter and slows down the aging of paint over time. Polishing should be done with professional machines and pastes from trained people. For maximum effect, the outside temperature and body temperature are determined.

Benefits Of Using Boat Polish?

Boat Polish ReviewsOf course, it is essential to know some of the main benefits of using one or another product. Let’s take a quick look at the benefits of the boat polish.

  • UV light protection – Most boats live a life under the sun. That means that they are exposed to long-term sun damage. Adding a ship polish coat will help prevent UV damage and preserve your vessel’s exterior color and quality.
  • Retention – Using boat polish will ensure that you enjoy the boat longer. Not only will it protect the color and the deck, but it will also give the vessel shine and prettier look.
  • Marine environment – Boat polishes are uniquely designed to resist the situation in the water. They will save the wood from corrosion and the sometimes harmful contact with the water.

There is a big difference between a boat and a car polish. Using a bottle of polish that you have on your boat for your car may be tempting. However, you will struggle to cut the defects with most automotive polishes into the fiberglass or gel coat surface. A much better experience will be provided by the use of a specific boat polish designed for the marine environment.

Polishing your boat may be a time-consuming task, but you can achieve impressive results with the right boat polish and technique.

Types of Boat Polish

The boat polish is categorized into three types – gel coat, fiberglass, and aluminum. Here is some more information about these kinds of polish.

  • Aluminum is durable and quickly resists polishing. You need to find a product which will work for this material. Make sure that you first clean your aluminum boat thoroughly to prepare it for polish properly. That means washing up debris and clearing off any dust that may have been collected. Then gently buff the surface and apply the product.
  • Fiberglass – here the steps are almost the same, but you should check if the polish is made for this material.
  • Gelcoat – The polishes made for gel coat are more abrasive than the others. Using them with other materials can be pretty dangerous, because they may get damaged.

There are also some products which work for more than one surface.


Like every other product, you have already chosen to maintain the coating of your boat, the boat polish should be selected carefully. Here you can have a look at the most essential features of the boat polish.

  • The polish must be specially made for boats. You should not use car polish. It is not resistant to the marine environment, and it will not protect the surface of the vessel from the negative influence of the water.
  • Adaptability – While the hull of a boat will generally be made all the way through from the same material, there may be various types of surface on your sailboat that you would want to polish. Boats usually have metal, gel coat, fiberglass or painted surfaces, and all of these materials require different treatments. If you have more than one element on your vessel, choosing a versatile polish, which can be used with all of them, can save you money and time.
  • UV protection – It is essential to look for this feature. If the polish is not UV-resistant, it will not keep the surface, and the facade will be damaged from the direct sunlight.

How to Use The Boat Polish?

Polishing the sailboat can be hard, but here are some tips for applying the polish and some easy steps on how to wax your favorite boat.

  • First of all, check the instructions. They will give you useful information.
  • Clean the surface, which you are going to polish. It should have no dirt or dust.
  • Use a buffer to smooth the deck.
  • Clean it again from the dust.
  • Apply the boat polish, as the instructions tell you to.

Depending on the size of your boat, applying boat polish can be very tiring. It is therefore recommended that you use a top boat buffer to apply the polish as it will make it easier to cover more of the surface and cut it into the fiberglass or gel coat.

There is no reason, of course, why you can’t use your hand to apply the polish. For those tricky to reach areas, some people may use both a machine and hand polishing. If you’ve got a big boat, however, it will take a lot of time and effort.


Now we are introducing you to some tips on choosing and applying the boat polish to your vessel.

  • Always check the type of boat polish.
  • Follow the instructions when applying it.
  • Clean the deck of the watercraft before starting.
  • Take a look at the features of the polish. Some of the essential characteristics of the product should be UV-resistance and marine application.
  • Use glasses and gloves while working with the polish.
  • Be aware of the time. Polishing your vessel can take you a lot of time.
  • You will need the right equipment: Not only will this save you some time, but it will also produce a better finish. You will become more experienced with practice, however, so don’t expect that you will achieve a perfect finish the first time you do this.
  • To eliminate old polish and dirt and grime, use strong detergent.
  • When you are ready with the polish, allow some time for it to dry.
  • After the polish dries, rewash it with some water and mild soap.
