The problem I have is not so much barnacles, but mussels. As Martin said, "mussels attach with a self created fiber." For the past 3 months, I have been praising Micron 66 for its effectiveness of preventing marine growth. Dwight suggested applying 66 to the prop. It is worth the try and here's one reason why I think so. Since 2006, I have used Micron CSC .....every thruhull was painted with CSC up a few inches with a foam brush....yet mussels grew in the thruhulls.....last year, the thruhull openings were painted with Micron 66......mussel growth was almost none existent. Something in the Micron 66 appears to be effective inhibiting mussel growth. So, I am going to paint the prop with Micron 66.....what have I got to loose.....a little paint. Wish I could paint the bottom of my keel with 66 as well....boat is in a cradle with the bottom of the keel sitting on a big piece of wood......we don't use a travel lift. Any suggestions on how to paint the keel bottom? Bob Abbott AZURA C&C 32 - 84 Halifax, N.S.
