Can I apply Interlux antifouling paint to my transducer?

Yes, it is recommended that you use a hard antifouling paint that does not contain Keytones. Keytones are found in Vinyl based antifouling paints like Baltaplate and VC Offshore. A good antifouling paint to use is Fiberglass Bottomkote or Fiberglass Bottomkote Aqua.
