Transducer Anti-Fouling

I was wondering what anti-fouling methods my fellow sailors were using on their plastic depth sounder transducers? I know Pettit has a transducer paint but that is for metal transducers.

Do you use bottom paint on it?
Is it effective?
Does bottom paint effect the transducers peformance?

I've never used bottom paint on my plastic (Airmar) transducers because the paint is solvent based and has copper in it. This year I'm using Hydrocoat which is water based paint but still has copper.

In the past I've used something called Green Grease which is a water proof axle grease that's worked pretty good. I think I forgot to coat the transducer last spring before launching and it was loaded .

Thanks for your replies.
