Reducing/Preventing Barnacles on Transducer?

Let me first state the manual says not to paint the transducer so that is out. Is there anyway to prevent barnacles from attaching to my transducer (transom mount)? Any spray, or solvent that will work?

Water based Transducer paint

You can use water based transducer paint with out harming the surface of your ducer.
Transducer Paint

Key Benefits & Features:
Improve your depth sounder performance. This water based antifouling tranducer paint resists marine growth yet does not attack the transducer face like some solvent based botom paints. A brush is in the cap for easy application. Black. 2oz.

The manual says not to paint - it does not differentiate between the MDR paint mentioned/transducer paint/bottom paint. I will try the MDR paint and be very careful with what it touches. Thanks for the help. What is powder pepper?

I am probably wrong but I believe years ago there where things mixed in the bottom paints that were said could affect your signal. I believe those paints were also toxic to the environment are not used anymore.
I also noticed with a recent transducer installation they mentioned not to paint. This I cannot understand as it would get covered by barnacles in the right conditions. Anyway for years I always used the little bottle of MDR painted the entire transducer top, bottom and wheel and never had a problem so I stick with it. I just can't stand the little brush that comes with it.

Most bottom paints (even today) contain copper. There is actually legislation being proposed in California right now to ban the use of copper in bottom paint. I'm not an electrical engineer, but it does make total sense that painting the bottom of a transducer with a paint that contains copper would indeed mess up the signal quite a bit.

Prior to the late 1980's all bottom paint was TIN-BASED. That stuff worked so much better than this copper stuff we have now except it was too toxic so Congress banned it. :( I know for a fact that painting a transducer with that tin stuff really messed things up too!
