Its ablative action wears away as you move through the water, continuously exposing a fresh layer of biocide to help deter barnacles, mussels, and other marine growth from attaching. Because the coating wears down over the season, there is no buildup along the hull, which can simplify prep work before the next coat and reduce sanding time.\u003c\/p\u003e\n\n\u003ch3\u003eSmart features and what they mean for you\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-season protection with copper biocide helps deter fouling in a range of saltwater conditions.\u003c\/li\u003e\n  \u003cli\u003eDurable finish stands up to trailering, beaching, and routine wear so you can keep boating with confidence.\u003c\/li\u003e\n  \u003cli\u003eSticks to properly prepared fiberglass, wood, steel, and iron bottoms and is compatible with most previous bottom paints.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eUnderdog is easy to apply by brush, roller, or spray.
