sex wax. a local diver put me on to this. my boat was in the water
but not being used much and every month i had to dive on the prop and scrape off mounds of barnacles
. a local diver recommended sex wax which i applied while the boat was in the water
. from that time until we went cruising four months later i never had a single
barnacle. i don't know if running the prop washes off the sex wax as once we got underway we used the engine
enough to keep the prop spinning.
what is sex wax? just ask any surfer. or google
it and buy a cake for about one dollar. i used the hard variety. and it can be applied while the
boat is in the water - not possible with a spray can....
