Combine it with a high-quality boat wax and you’ll be able to not only restore the look of your watercraft in no time, but also to protect the paint finish from harm.

Benefits Of Polishing Your Boat

If you are looking into getting into boating and you’re considering purchasing a yacht or another type of watercraft, you should do a bit of research on the type of gear that you will need after purchasing it. Here is a list of benefits that you will enjoy if you buy a polish that’s worth every penny.

1. Improve The Looks of Your Boat

Polishing removes the pitted surface of your boat. Both buffing and polishing compounds are, in fact, abrasives, so they are capable of restoring the shine of a boat’s fiberglass gel coat, for instance.

Boat polish can remove discoloration, scrapes, and imperfections from the surface of your watercraft, and it can also increase the body shine. In other words, such a product can make it possible for your boat to look as if it were brand new.

There is a procedure that some boaters use. They apply pure boat polish and then they wax the surface of their vessel. This makes it possible for both products to retain the high gloss of the paint. It is worth noting, however, that this type of polishing works only if the boat needs only superficial refinishing.

Rubber compounds are necessary if the surface of the boat is extremely dull.

2. UV Light Protection

Boat Polish ReviewsIf you use both polish and wax on your boat, you can get all the benefits of UV protection. We couldn’t help noticing that there are many articles out there that misinform people by telling them that the products themselves have UV protection properties.

Unfortunately, that is not true. Polish removes part of the debris and pitted surface on your boat, so it exposes the vessel even further to UV damage, if it sits outdoors all day long. That’s why boat polishes and waxes are often used together. Make sure to pick two compatible products.

3. Contaminants Protection

This is the same as in the case of UV protection. It is true that boat polishes are made to put up with the abuse of water, no matter if it’s freshwater or saltwater you’re doing your boating in. A polish can protect the wood on your boat, for example, or other parts, provided that you pick either a cleaner wax or a polish and a wax at the same time.

This formula is capable of removing chalking and heavy oxidation from either bare or painted aluminum. It’s apparently also able to restore the color and shine of the surface. Before using the product for the first time, it is advised to test it out on a small surface ahead of utilizing it on the entire boat.

What’s worth noting about Meguiar’s alternative is that it is fully capable of removing water spots, scratches, oxidation, and stains. Your boat looks better and gets a rich gloss after this treatment.

  • Removes heavy oxidation

It can also help repel stains and dirt over time, which will make further maintenance as easy as pie. However, it is worth adding that the manufacturing brand recommends using a buffer for the application process so that you are able to cover the whole surface of the boat evenly.

  • Cleans stains and repels dirt
  • Made in the United States

What Is A Boat Polish?

Best Boat PolishBoats need regular maintenance just like your house. Regular checks on your battery’s health, along with the safety and condition of other boating equipment that you use can make it possible for you to make the most of your boat in the long run.

Boat polish is a type of product that allows you to protect the coating of your boat from things like oxidation and corrosion. These can become real problems after a while, especially if you don’t pay attention and leave your vessel to rust. Sealing and polishing a boat can prevent these issues.

1. Ingredients

If you have ever considered getting a boat wax, you might have asked yourself how come you should also purchase a polish, too. Well, boat polish is a little different than your typical wax. It is a synthetic mix that’s used on new watercrafts or after any oxidation has been removed from older ones.

Boat polish is also capable of protecting your vessel against UV damage. Most of the products that we have come across effectively transform your hull into a non-stick surface. These are things that boat wax just can’t do.

2. Use

Unlike wax, boat polish should almost always be applied with machines and devices. If you don’t have any experience in this field whatsoever, you might have to ask a professional to do it. That means that you risk spending more money, but it’s still a good idea to polish your boat when you notice the first signs of corrosion.

Boat Polish Types

There are different types of boat polishes out there but the difference between one another stands not in the quantity, but in the ingredients and the type of material that they are crafted for. Let’s look at some of the most common ones.

1. Polishes for Gelcoat Surfaces

These are a little more abrasive when compared to the other two that we have mentioned here. Because of this, you should avoid utilizing them on other types of surfaces and more specifically, avoid using the same boat polish on your car.

2. Products for Fiberglass Hulls

Fiberglass doesn’t call for that much care and attention compared to other boat surfaces. However, it is a good idea to pick an option specifically designed for this type of hull so that you don’t risk producing damage to your watercraft.

3. Polishes for Aluminum Boats

Aluminum is the most problematic type of boat surface that you might want to polish. Finding a product that is absolutely compatible with this type of hull is paramount. Otherwise, you risk damaging your boat to the extent that it becomes unusable.

Besides, applying a boat polish on an aluminum hull requires a bit of cleaning and maintenance beforehand. Make sure that the surface is debris-free so that the polish does its job properly. Then just buff the hull and apply the polish of your choice.

Boat Polish Buying Guide

Boat Polish Buying GuideBoats that spend a lot of time on the water and they have no cover placed over their surface can significantly suffer from the marine environment and UV damage.

That’s how your watercraft might end up with things like scratches, oxidation, bird dropping, and a variety of other defects that can ruin your boat’s overall appearance. If you are in the market for a good boat polish and it’s the first you’re thinking of getting, you might be feeling confused as to which features matter the most.

Here is a comprehensive guide on all of the aspects that you should keep in mind before deciding on a particular unit.

1. Marine vs. Auto Polish

As tempting as it might be to use a regular bottle of polish that you might have already purchased for your car, that might not be the best idea in the world. The product will find it very hard, if not impossible, to cut into the gel coat or fiberglass surface so as to remove its defects.

Most auto polishes aren’t capable of doing the same things as polishes made specifically for watercrafts. They are primarily designed for painted surfaces.

Utilizing a specially made boat polish makes it possible for your vessel to put up with the abuse of the environment it will spend most of its time in. Not only will the boat polish protect against water spots and UV rays, but a lot of other damaging factors, too. In the end, using a marine boat polish is safer and more effective.

2. Application

There are two ways of going about things in terms of how you can apply the product on your boat — by hand or by using a device.

If you have a large boat, you shouldn’t even try to apply boat polish by hand. First, it will be a lot more exhausting than you might imagine. Second, there is no way of knowing you will apply it correctly, and you might risk causing damage to your hull. Seek out the services of a professional if you have zero experience at this.

Using a buffer is a lot more convenient and easy and you can apply the polish faster. This machine effectively enables you to cover more of the surface in a timely fashion. It also allows the substance to cut into the gel coat of fiberglass more easily.

Professional detailers recommend using limited pressure and setting your machine to spin at about twelve hundred to fifteen hundred RPM so as to cut into the boat surface.

If you don’t feel like using the buffer can be done for the entirety of the surface, you can apply the polish by hand in the areas that are harder to reach.

3. Buffing

Getting rid of the oxidation that your boat might be suffering from doesn’t call for the use of the strongest polish available for sale these days. Buffing the boat can be done with the least abrasive product that you get your hands on so that you can gauge the results and see whether a stronger one is needed.

In fact, you can use a more powerful polish for those areas that are heavily stained only. Restoring your boat’s shine is extremely easy. You should consider regularly polishing your boat if you notice any damage whatsoever so as not to affect its resale value in the long run.

4. Adaptability

Boat Polish AdaptabilityChoosing a versatile boat polish, one that can be applied on a variety of hulls, is the right way of going about things. If you pick one that’s solely made for one type of surface, you should know that it’s not going to work on all of the areas.

Boats nowadays aren’t made with surfaces constructed of a single material. In fact, most boats have areas made of metal, fiberglass, and gel coat on the same watercraft. Keep that in mind when choosing your boat polish, whether it is cheap or not.

5. UV Protection

This type of feature doesn’t even need to be described. It is an essential characteristic that you should look for in all of the products that you purchase for your boat’s hull. The sun can inflict a lot of damage to your watercraft, and it can definitely negatively affect its resale value.

Ideally, you should avoid storing your boat directly in the sun unless you apply boat polish and boat wax regularly. Some boaters use these products every 4 to 6 weeks just to be on the safe side of things and make sure that UV damage isn’t something they have to deal with.

6. Boat Damage

Choosing the right type of polish should also be done after you assess the imperfections and level of damage of your boat’s exterior surfaces. Dry or flaking paint or big scratches can be fixed with a formula that’s applied with a buffer.

Smaller defects, on the other hand, can be polished out with a little elbow grease and a cloth. Specific formulas might be required for other types of damages such as water sports, stains, oxidation, and mineral build-up.

7. Environmental Factors & Boat Storage

The place you store your boat in on a regular basis has a significant effect on the conditions that it faces every day. Boats that are stored indoors and out of the water are generally better protected against oxidation and corrosion, especially when compared to those that are on the water day in and day out.

These boat storage and environmental factors should be given some thought to before you decide on a product.

How To Polish A Boat

How To Polish A BoatPolishing your boat can be a little challenging, especially if you have never tackled the task before. We decided to put together a list of tips that you should rely on each time you want to go through this process.

1. Before Polishing Your Boat

Clean your boat’s surface as best as possible so that no dirt or dust are present. Use a buffer to smooth your deck and then clean it once again so as to remove any contaminant whatsoever.

Make sure to read the instructions that you have received along with the boat polish that you’ve bought. Doing this can save you a lot of trouble in the long run. Don’t just rush in and apply the polish if you haven’t gotten informed before.

2. Protection

Take a look at the polish features to make sure that it is made specifically for boats and that it can offer your watercraft UV protection. Use protective gear while applying the product, which in this case would mean wearing protective glasses and gloves.

Use the right kind of equipment. If the instructions state that you should utilize a buffer with the polish, don’t think that you can go against them and apply it by hand. This might sometimes not work.

The products in this category differ a lot in terms of viscosity, in particular, so you might really have a hard time spreading out the polish as best as possible, if you just use your hand and a cloth.

3. Final Cleaning

Once you have done your best at applying the polish, wait for a while and leave it to dry. If the product calls for an application of boat wax, too, do that, as well. When all of the process has ended, make sure to rewash your boat using tepid water and mild soap.

FAQs About Boat Polishes

1. What Is The Difference Between Polish and Wax?

Wax and polish are two very different substances. Compared to wax, polish is abrasive, and that’s why it is capable of removing oxidation and corrosion from the surface of your vessel. Polish is specifically meant to remove imperfections and contaminants.

On the other hand, wax acts more like a protective coating. This is the reason why it is highly recommended that you wax your boat right after polishing it so as to protect it as best as possible. A polished boat surface has the perfect adhering capabilities for you to apply wax on it.

2. How To Polish A Boat With A Buffer?

You are allowed to polish your boat without using a buffer, but keep in mind that the results that you are going to get might be less satisfactory. If your boat has sustained scratches or damage only in a specific area, you can use a microfiber (or any other soft) cloth to apply polish and then wax that specific area.

If your boat’s hull has contaminants and imperfections in general and across its entire surface, you should always use a buffer.

3. How To Polish Aluminum Boat?

Use a specific aluminum cleaner for the best results. If the boat polish isn’t made for aluminum boats, don’t invest in it. It is not going to have the same efficiency.

The rest of the steps are rather similar to those that we have showcased in the section on how to polish your boat. This means that the surface has to be as clean as possible before you apply the product. Apply your favorite aluminum-grade polish with as much consistency as possible without overworking or under-working an area.

After buffing consistently and effectively everywhere, your boat should have a consistent shine. Inspect your watercraft fully to spot any nooks and crannies that you might have missed. Take care of them now if you have rented the buffer and it doesn’t belong to you.

4. Can I Use a Car Polish On My Boat?

You can try, but it is not made for the same types of surfaces on most boats out there. Therefore, it is not going to provide you with the same results as a product made specifically for marine watercrafts.

Even though car polish is cheaper, we urge you to consider getting a boat polish made for your type of hull, just to be on the safe side of things.

Wrap Up

Hopefully our guide, along with our boat polish reviews, have helped you understand what features you should focus on when you are in the market for this type of product again.

Finding the best boat polish can sometimes be a matter of trial and error. If you haven’t consulted any other resources, you could use YouTube, where there are a variety of tutorials on how to polish your boat.

A boating forum might be helpful, as well, as you will find there a lot of opinions from boaters that are more experienced and that might have tried out a lot of products over time.

  1. Premium Marine Polish of Star brite, this is a great wax for gelcoat. I have used this exclusively on my jet boat for many years. While it won’t fix the oxidizing metal flake, the straight gelcoat color is excellently polished and shines like new(when compared to the areas that are covered by various panels or beneath the “sun-line.”
    Highly recommend!
