When I first had my boat, I was told it was no use painting antifouling onto the shaft and propeller as is would simply be spun off. I heard tales of lanolin and all sorts of solutions. After the first season with my new expensive MaxProp coming out covered in barnacles, I had it cleaned and burnished and tried lanolin. The next year, I just cleaned off the barnacles and antifouled it. Antifouling paint may not stick on a new burnished propeller blade but it sure sticks on the residue left by barnacles. Since then the antifouling sticks and the barnacles don't.
I read somewhere that scientists are trying to isolate and manufacture barnacle glue, apparently its the strongest known adhesive. It sets underwater too.
