Product Overview

TotalBoat Underdog Marine Antifouling Bottom Paint is an excellent product that provides full season protection against barnacles and other marine fouling organisms. This paint is ideal for sailboats, power boats, fishing and work boats in all types of saltwater conditions. The ablative coating allows fresh biocode to be released continuously so that it can combat any marine fouling while reducing the amount of paint buildup.

The product is easy to apply with a natural bristle brush, a 3/16 nap or foam solvent safe roller, or airless or conventional spray equipment. It is available in gallon size in black, blue and red colors and covers up to 500 square feet per gallon. This paint should only be used on properly prepared fiberglass, wood, steel, iron and previously painted surfaces in good condition. It should also only be applied to hulls and boat bottoms below the waterline.

I have been in the marine industry for over 15 years and I have seen a lot of antifouling bottom paints come into the market.
