Behind the skeg where the rudder stock is, my rudder seem to have some damage. It appears the fibre reenforced plastic has lifted off on the port and starboard sides exposing the stock in a few places (largeish areas). Although they aren't deep it appears to me that it was just a thin plastic layer laid on the metal stock and has become detatched. It doesn't go around the stock between the back of rudder and skeg, so can be accessed with rudder attached but makes it difficult to work on?
Would taking the rudder off to effect repairs be a good idea and if so how difficult to remove the rudder? Also what would be the best way to repair the damage, grp resin with a thin fibre matt or something else? Thanks to all who take the time to answer.
