[C320-list] Prop paint

[Scott Thompson]

This sounds like a possible solution for me. Do any Chesapeake sailors 
have experience with this approach? Pacific waters tend to be colder and 
saltier than what I experience in Maryland, so results could differ also.

Then I coat the propellor with Lanocote as a further precaution.  So far over the last 5 years of using this system, it has kept barnacles off on these parts.  I check it every 6 months with new zincs and that system works well.

We tend to not use our boat much during latter part of July and August, and inevitably the warm waters of the Chesapeake Bay encrust the prop during this period. Scraping the prop then takes off the expensive PropSpeed. Plus two years ago I nicked a finger while scraping the prop and got a bacterial infection that eventually required surgery and months of antibiotic treatment. My doctor tells me to not go under the boat any more.
