  • Racing sailors use a thin layer, self-polishing antifouling, that becomes gradually thinner season.
  • Wadvaarders regularly dry up should also use a hard, rugged bottom paint; the gentle, self-polishing antifouling paint with fast drying wear.

How do You Use An Antifouling?

  • For good coverage of the base color, apply two coats.
  • Make sure applied to the areas where water hull to endure the tough get an extra thick layer. Especially under the waterline, rudders and stern with experience extra wear
