At first I painted the through hulls with the antifouling transducer paint. I then bit the bullet and sprayed the housing for the speed and the entire depth transducer with VC offshore. I pull the speed sensor and insert the plug whenever I leave the boat. There is a warning label that tells you not to use paints with strong solvents on the transducers. I haven't had a problem. The speed sensor gets cleaned and hand painted with the transducer paint yearly.
