The surface of the FRP surface, which was shiny at the time of the new boat, will gradually deteriorate over the course of 5 to 10 years. “Hull paint” and “Outer panel paint” are used to remake it cleanly. For land storage, apply this “outer panel paint” to the entire surface including the bottom of the ship. At this time, if any paint on the bottom of the ship remains, remove all the paint and then apply the “outer panel paint”. If you are mooring at sea, paint the bottom of the ship and paint the hull with “outer panel paint”. Note: If the “outer panel paint” inadvertently adheres to the painted surface of the bottom of the ship, the antifouling effect will be reduced, so be sure to guard it properly with a vinyl sheet or newspaper before painting.
