Economical and effective antifouling protection
Underdog releases its 24% copper content at a controlled rate to keep heavy soft growth, slime, algae, and grasses at bay for a full season. It’s an unheard-of value in the world of bottom paints.
Easy to apply – even over existing paint
A sanded, cleaned surface in good condition is all Underdog needs; it doesn’t matter if it’s going over last year’s paint. Just stir, pour, and apply by brushing, rolling, or spraying. Underdog has great coverage characteristics, and adheres extremely well to fiberglass and wood.
Resists abrasion from trailering, beaching, and light scrubbing
Underdog’s ability to thwart barnacles and slime works best on boats that see frequent use, and its durable, ablative finish stands up well to trailering.
