Re: Using Bottom Paint on Brass Propeller
What Maine says is right. For that reason I make sure that I prep the prop with underwater metal primer prior to any coating of Cu bottom paint. I've used such a system for over 20 years on my expensive max prop and it stays effective for the 2 or sometimes 3 years between haul outs here on the Chesapeake.
