Furuno CH-300 Installation Manual page 27

Note 2: When the soundome is painted (to keep marine life off the transducer),
observe the following precautions:
Use only anti-fouling paint type MARINE STAR 20 (Manufacture: Chugoku
Marine Paint Co., Ltd., Japan).
Paint only the plastic portion of the dome. Painting the metal parts causes
electric corrosion.
20. Clean surface of gasket, tank flange and shaft sleeve, and then coat flange
gasket with ADHESIVE 1104 200G.
21. Lightly coat bolts, nuts and washers with KINORUSTER.
22. Set the hull unit into the retraction tank, taking care not to damage the
