How to Choose a Boat Wax: Buying Guide

Buying a high-quality boat wax is important because it will protect your boat from damage in the long run. It also makes your boat look great. So, it’s best to invest in a good boat wax. Here’s a guide on what to look out for when choosing a boat wax:

  • Type of boat you own

The type of boat you own plays an important factor. If your boat has a fiberglass surface, pick a boat wax that’s best for fiberglass. If your boat has a gel coat surface, pick a boat wax that specifically works for a gel coat. This is because each boat surface has different properties, and each boat wax matches these properties. Always get the one that’s suitable for your material. The material is usually mentioned on the labels. Never use car wax as boat wax!

  • Does it remove oxidative damage?

Some waxes remove oxidative damage, while others don’t. If your boat is suffering from a great degree of oxidative damage, choose a wax that is better at combatting that damage. If your boat doesn’t have any significant oxidative damage, you can choose a lighter wax.

  • Durability

This is one of the most important aspects when choosing the best wax for fiberglass boat. After all, you can’t wax your whole boat multiple times in a year. Most people just do it once or twice a year. Therefore, it’s important that your wax is long-lasting and durable. Otherwise, the wax will wear off in a while and it won’t provide long-term protection. All of the waxes listed above have high durability, so you don’t need to worry when buying them. For other waxes, you need to try and test them first.

  • Quantity of Wax

You should know the average size and surface area of your boat so that you can calculate approximately how much of the wax you’ll need. Some waxes come in 1-liter bottles while others come in smaller bottles. Get the number of bottles according to the size of your boat.

  • Application Method

Some of the waxes are suitable for both, application by hand or using a machine. However, not all of them are suitable for machines. Therefore, make sure you know which wax you’re buying depending on how you plan to use it.

  • Finishing Gloss

Some people like their boat shiny and glossy, while others like their boat with a matte finishing effect. Choose your boat wax according to the type of finishing look you want! Most of the products listed above give a shiny and glossy end look. This makes your boat look brand new and enhances the color of your boat.

  • Type of bottle

If you’re looking for a quick fix and don’t have enough time to pour wax over a cloth and then over your boat, it’s a good idea to buy one that comes in a spray bottle. All you have to do is spray the wax onto your boat and you’re done! It saves a lot of time and is more convenient to use.

These were the most important factors you need to consider so that you can get the best wax for fiberglass boat!

What is the best wax for a gel coat?

Most new boats have a gel coat. The high-tech latest formulas of all the boat wax listed above work great on gel coats. They protect your get coat and prevent UV damage.

Is boat wax different from car wax?​

Yes, boat wax is different from car wax. Car waxes are less resistant and they don’t fix oxidative damage.

Do I need any additional tools for marine waxing?​

There are a few tools that will make the entire process a lot easier and quicker for you. First of all, to clean the boat, you can use a jet cleaner. A jet cleaner/washer uses high pressure to remove dirt and debris, giving you a clean boat for you to wax on.

Next, to apply the wax, you can use the help of a buffer! A buffer will make the waxing process a lot easier and quicker.

Why can’t I use my car wax on my boat?​

Cars don’t have to spend hours in the water, which means you need a stronger wax for boats that is able to withstand harsher conditions. Car wax also isn’t great at removing oxidative damage, which is much more commonly found on boats.

Moreover, boat surfaces have to deal with water spots and fish blood stains, which are very hard to remove. Typical car waxes aren’t designed to remove these stains. Boat waxes provide longer-lasting protection!

It’s better to avoid using car wax on boats as it could damage your boat in the long run.

Why do I need to wax my boat?​

Your boat is continuously exposed to UV rays from the sun, saltwater, harsh environmental conditions, grains of sand, fish blood (in case of live fish catch), dirt from passengers traveling on the boat, residue stains and many other factors. These deposit dirt on your boat and leave behind residue.

UV rays, in particular, are extremely harmful to your boat. They impart oxidative damage on the surface of your boat. Since your boat gets UV rays all the time, it’s important to apply a wax coat to your boat.

This wax coat makes sure stains and other dirt don’t stick onto the boat. It provides a protective barrier for the boat and even prevents UV damage. Applying wax onto metal surfaces will prevent them from getting into contact with water. This prevents the metal from corroding.

Last but not the least, waxing your boat will make it look shiny and glossy like it’s brand new!

How should I prepare my boat before waxing?​

Before waxing, you need to make sure that the boat is completely clean. Rinse the boat using any suitable cleaner. This removes dirt and debris. Some cleaners are also designed to remove oxidative damage. Next, dry your boat and make sure it’s out of water.

After your boat is completely clean, you can wax it. The cleaning process is important. Don’t skip it. Otherwise, there’s no point in applying wax to a boat that’s already dirty. The wax will just let the dust and dirt settle in.

How often do I need to wax my boat?​

While the exact waxing frequency depends on your usage, it’s a good idea to generally clean and wax your entire boat about twice a year. Not doing so can have harmful effects on your boat. If you use your boat too often, then it’s a good idea to increase the frequency! However, at least two wax rounds (along with cleaning) are more than enough.

Steps of Waxing a Boat

While waxing a boat is no easy task, you can follow these steps to get the best results out of your waxing session:

  • Get your boat securely out of water and onto a ground where you can easily work.
  • Give your boat a good rinse using only water. It’s best to use a jet washer for better results. Always make sure you start washing the boat from the top then make your way downward! This way, all the residue that goes down is also washed away eventually.
  • Your boat should be clean before you start waxing it. Otherwise, sand and other particles left on your boat will scratch your boat’s surface while you’re waxing. To clean the boat, use any suitable boat cleaner like the one in the Pilo Glow Kit listed above. Different cleaners target different levels of oxidation, so choose your cleaner accordingly.
  • Rinse off the cleaner with water.
  • Let your boat dry. Make sure it dries in the shade and not under the sun because UV rays from the sun are not good for your boat.
  • Start waxing your boat. Focus on one section at a time. The wax dries quickly, so if you focus on a bigger area, one part will dry before you get the chance to apply the wax on that part.
  • After the wax has dried, wipe off the excess wax from each section using 100% cotton microfiber towel/cloth.

That’s all! Your shiny, glossy boat will be ready! It takes patience, but it’s definitely worth it!
