Product characteristics
Description
A biocide-free spray, Ecopower Prop is used as a coating for
propellers and outdrives. This coating makes it difficult for fouling to
fully attach thus making it easy to dislodge and remove when
cleaning. Advanced binder technology controls the self-renewing
effect throughout the season, without paint build-up.
