There are many different boat paints and qualities, generally the more you spend the better the results. There are a variety of types including topside and bottom paints. Topside paints are meant to be used above the waterline and will not hold up under water. Bottom Paints (also called antifoulants or antifouling coatings) are pesticides that are only used below the waterline when you are trying to stop growth from occurring while your boat stays in the water over long periods of time.

The type of paint you choose for your boat will depend on the type of boat you have and the environment in which it will be used.
There are two main types of boat paint: antifouling and topside. Antifouling paint is designed to prevent marine growth from attaching to the hull of the boat, while topside paint is designed for the superstructure of the boat, such as the deck and cabin.
If you plan on using your boat in saltwater, it is important to choose a paint that is specifically designed for saltwater use. Saltwater is much more corrosive than fresh water, so a saltwater-specific paint will be more durable and longer lasting.
Using your boat in freshwater, will require a different paint. There are a few different types of paint you can choose from. Freshwater-specific paints are available, but they are not necessary if you do not plan on using your boat in saltwater.
