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.

Duralux High Gloss Marine Enamel is affordable and easy to apply and only recommended for above the waterline or moderate use on the bottom (a day or so in the water, not extended periods). This topside paint works best in very thin coats; see the prep recommendations found on product page on “how to use” tab. Duralux marine enamels do have a color offering in a flat finish, those are limited to their camouflage paint colors. Marine Alkyd Enamels like Duralux and Blue Water Marine are effective and low cost. There are a variety of brands styles and even include a water-based enamel.
Next, you also have a choice of marine paints that can be used above or below the waterline and come in a few different styles. Revolution boat paint (a great option if rolling/brushing) or Mono Epoxy (durable and looks best sprayed) are the easiest to use and are best primed with the Etching Primer (SM 664D) for the primer. They are also available in your choice of sheen (satin or gloss). Click on “view more” for the paint and use the specification/how to use tabs for detailed instructions, coverage and preparation on any of the product pages. The “work horse” is the Two Part Epoxy, most durable of the Supermarine choices with the top of the line selection is Supreme Urethane. The previous two paints are available in flat and semi gloss as well as satin and gloss, and perform better than a marine enamel and poly enamel, but with a little higher cost.
The best performing and hardest application is either Awlgrip or Awlcraft 2000. These require a more technical application and require the use of proper primers, catalyst and thinners with each application.
Typically when people discuss bottom paint on a boat they are referring to Antifouling paint. Bottom paint prevents growth of organisms that attach to the hull and can affect a vessels speed, performance, and durability when boat is kept in the water for extended periods of time. If you don’t have that problem, you may not need bottom paint. Antifouling bottom paint typically has a flat, dull finish that is used below the waterline.
There are generally two types of bottom paint both of which have several variations that create a multitude of products in the market place. The two different types or categories of bottom paint include hard bottom paint and ablative bottom paint. Related Article> What is the Difference Between Hard and Ablative Bottom Paint.
So your boat paint choice depends on your budget and which paint meets the needs of your boat and usage.
