There are many different topside boat paints and qualities, generally the more you spend the better the results.
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 does have a limited color offering in a flat finish, but those color choices are limited to their camouflage paint colors. For use on aluminum the Duralux Zinkromate Primer is recommended and for use on wood the Duralux Yacht Primer is recommended for best adhesion.
Aquagard offers a water based enamel, Aqua-Gloss, for customers that want to avoid solvents or restricted waterways/marines that don’t allow solvents. The Aquagard paints are available in several high gloss colors for use on fiberglass, aluminum and wood. An easy to apply 190 Waterbased Primer is recommended for aluminum or wooden surfaces with use of the Aquagard 180 Wash and Dewaxer.
You also have a choice from Top Secret Paints that can be used above or below the waterline and come in a few different styles. The TS-100 Silicone Epoxy (great option if rolling/brushing) usually customers choose the Etching Primer (TS 664D) for the primer. 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 Ever Last Epoxy and the top of the line selection is Supreme Urethane and the only one recommended for long periods under water.
The best available boat paint for the topside with the best finish is Awlgrip, most expensive but best results and loved by customers. Awlgrip marine paint also requires a little more “do it yourself savy” to apply these paints, and require the correct activators and reducers when applying. The manufacturer of Awlgrip recommends it for above waterline use only.
Your topside boat paint choice depends on your budget, the durability needed and the amount of time you want to spend on your boat paint application.
