Prop Coat Barnacle Barrier 1792 is now available in a quart-size can and, as always, can be used on all underwater metals, including saildrives, shafts, strainers and folding and non-folding props. Two or three coats are recommended, after which the coating will purportedly prevent hard growth attachment for up to 12 months. The dried film of Prop Coat contains an especially high concentration of zinc and self-cleans in service. It can be used above or below the waterline and is also available in an aerosol spray can. A fast-dry formulation makes it possible to apply multiple coats in quick succession, though it's still best to allow 24 hours before launching. From $99.
