[C320-list] Fouled Prop?

[Joe Geiger]

Thanks for all the advice.  I hired a diver to clean it off before our upcoming 2 week cruise to Provincetown, MA. We’ll be using her lots over vacation so creatures won’t get a chance to take hold. 

I did some research on-line and found that Rust-oleum Cold Galvanizing Compound has given people some good results.  They say it is similar to the Petit but 1/3 the price… even at West Marine.
