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 over existing paint. Dries fast.

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 paint with a brush or roller. It has great coverage characteristics, and adheres extremely well to fiberglass and wood. Depending on the temperature, Underdog can be dry to overcoat in as little as an hour, letting you can finish faster and launch the same weekend.

Resists abrasion from trailering 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. If your boat does sit stagnant after painting, Underdog’s antifouling abilities are easily reactivated with a light Scotch-Brite™ scrub down.
