Latest posts by Boat Bub Team (see all)

Boats are one of the most stunning and beautiful water vessels globally, making them a popular tool for tourism, travel, and fishing. The water vessel looks gleaming when adequately taken care of with proper boat care skills. When a boat is neglected, it loses its shine and may start rusting. One of the essential skills in maintaining your boat’s viability is to regularly polish your craft with the best boat polish you can find.

The kind of boat polish you employ for your bought polishing will determine your boat’s longevity and if it will shine and withstand the salt or marsh water.

There are several types of boat exterior that your boat is made out of fiberglass, aluminum, fiberglass, and a paint coating. Fiberglass surfaces have a special resin called gel coat that gives the boat its color and shine. When the surface is exposed to the sun and marine environments, it starts eroding its soft exterior, reducing its brightness and looking chalky.

As the gel ages, it also loses its essential oils, making it weather-beaten, dry, and worn out. Polishing the fiberglass exterior restores the oils to bring back the boat’s luster, removes swirl marks and scratches to keep the shine brighter.

Just as fiberglass paint applied on a boat’s exterior contains oils and emollients that make the vessel glow. The paint dries when exposed to the sun and water losing its initial shine. Polishing a boat’s surface with suitable polish helps to restore emollients and extend their life.

Benefits of Boat polish

Boat Polish

We have explored boat polish and boat polishing basics and have some food reasons you should buy boat polish for your yacht, boat, or water vessel you have. From many boaters and scientific research, it has been noted that boat polishing:

Improves the Cosmetic look of the boat

Whether You plan to sell your boat or use it for long, you want to have a beautiful surface with no blemishes. The best way to get the high price for your bought is to ensure it looks sparkly when you want to put it out on the market. You can ensure that its cosmetic outlook is on another level by providing that the boat is polished to remove the pitted surface. 

The buffing and polishing compounds are abrasives capable of restoring the boat’s fiberglass, metal, or plastic shine. You can use boat polish to remove discoloration, imperfection, and scrapes on the watercraft’s surface to enhance the body shine. That means using the boat polishes can restore your watercraft to look brand new.

When you need a superficial or cosmetic way to make your craft look new, look no further than a good polish with a quality product and finally wax the vessel’s surface.

Polishing and waxing help to retain the high gloss of the exterior boat paint. You may use rubber compounds if the boat is exceptionally dull to enhance the look.

Reduce the Ultraviolet effect on the boat

The sun is one of the biggest culprits that reduce the craft shine by weakening the plexiglass, paint, or fiberglass. A rein on the harmful UV radiation can ease your worries and keep your boat glossing as new. Most of the boat polishes have UV protection; however, to make the most of the UV protection, it is advisable to use both polish and boat wax.

Not all boat polishes have UV light protection; however, landing on the suitable boat polish can ensure you no longer have to worry about UV light. Boat polishes without UV light protection can exacerbate the UV light by removing debris and pitted surface from the boat surface to expose it to further UV damage. Always pick a boat polish and boat wax that are compatible for the best results.

Protect the Boat surface From Contaminants

The boat’s exterior surface protects the boat from contamination caused by environmental factors. When the vessel’s external surface wears out, it exposes the wood or metal to contaminants that can quickly reduce a craft’s shelf-life.

Boat polish can help protect the vessel whether it is in a freshwater or saltwater boating environment. Like the UV protection feature, you have to ensure you choose compatible boat polish and boat wax at the same time to ensure that the feature works properly.

How to choose Boat Polish

Boat polish is necessary for your watercraft, and you should make some effort to have a boat polish to clean your yacht or canoe. You must, however, be cautious that not all boat polish is suited for your boat. Here is a guide to ensure you choose the suitable boat polish for the right set of circumstances.

Stay Within Your Budget

While a boat polish is not likely to bankrupt you, it is wise to choose a bought polish with the most effective results for the right price. You can benchmark several boat polishes and compare the prices that give you the most value for your cash. Also, avoid cheap polishes that have no real effect on your boat. They are a waste of money you are trying to save.

Consider the material of your boat exterior


Every boat exterior is different. One of the most distinctive features of a watercraft exterior is the material finish. Some of the most common material finishes are metals like aluminum, plexiglass, fiberglass, plastic, and paint coat.

The different surfaces react differently to the materials in the boat polish designed for another material. If your craft has a metal finish, then only pick boat polish intended for metal surfaces.

Long-Lasting finish

Boat polish acts as a preservative in most instances, protecting your vessel against corrosion, peeling off of the outer coat, or looking dull. There are good boat polishes that give your boat a shine in a short period, and then the effects wear off as quickly as they got applied. You have to settle for a polish that has consistent results despite the time.

Protection From UV Rays

You deserve a polish that will protect your watercraft from elements that cause its exterior to fade or dull out after some time. The UV protection feature is about solving the problem from the root cause rather than cosmetically handling it. You should pick a polish that has UV protection to keep the boat hull protected. 

Eliminate Scratches

The hull is susceptible to scratching as it loses its paint or the fiberglass wanes. An appropriate polish should eliminate any visible and invisible scratches on the shell. Many irresistible boat polish options can help deal with scratching for good and cover up the blemishes to leave the boat looking as good as new.

Easy to Apply

It should be easy to apply your boat polish easily using either a machine or cloth. If you have to use highly sophisticated devices to apply the boat polish, then the boat polish is not worth the hassle. Pick polishes that you can apply at home or the marine without any professional help.

Protect surface from Weathering

The framework can easily be affected by adverse weather conditions, particularly the sun and the marine water, which are notorious for wearing the boat surface.

The polish that protects the boat surface from weathering has essential nourishing oils that restore the boat’s shine and rejuvenate dried craft paint; they lack filler and, at times, can repel the environmental pollutants.

Question: How do you remove oxidation from painted aluminum boats?

Answer: Oxidation is a severe problem to your boat as it leaves it looking unclear due to spots and chalky surfaces that result from oxidation. If left unchecked, it can accelerate the deterioration since the oxidized layer holds much more water.

Oxidation, chafe, and other stubborn stains can be removed from non-surface treated aluminum surfaces using a fine-grade abrasive polish. When the polishing is done, the aluminum surfaces are protected by protective oil or wax products.

Question: Should I wax or polish my boat?

Answer: Most boaters assume that you should always wax your boat and polish it at the same time. This belief is somehow misleading as a new boat waxed at least twice a year may never need polishing.

When the boat is not regularly maintained, it starts to fade, loses its shine, and becomes chalky. When such events happen, you need to polish your watercraft. The polishing should be immediately followed by waxing.

Question: How can I make my old boat shine again?

Answer: You can restore your boat’s shine with simple polishing. Use a soft piece of cloth or buffer machine until the hull has a glassy appearance. It is advisable to wax the boat immediately after polishing to guarantee long-term results. Luckily most boat polishes include wax in the package.

Question: How do you restore faded Gelcoat on a boat?

  • Answer: It is easy to restore faded Gelcoat on a boat with three simple steps.
  • Clean the boat surface, washing the boat hull and topsides with marine soap in diluted water.
  •  You should let the boat dry and start polishing to remove stain and oxidation to restore the shine.
  • It would be best if you protected the boat from losing its shine with wax.

Question: How often should I polish my boat?

Answer: A good boat maintenance regimen involves washing and polishing the boat to remove stains and keep it clean. One challenge is that it is often difficult to determine what is regular. A recommended period is 3 to six months though there are polishes that can last a whole year.


Your boat needs only the best boat polish to keep it shining, along with a few practical maintenance tips. The best polish is one that is compatible with the watercraft’s exterior as well as other substances like wax.
