Brad;
Many thanks to you sir!. When Brad sent the photos to me with others, I noticed cracking of the exterior coating with a white suface underneath. I instructed Brad to chip away at the coating to see if was gel coat. In additon, I asked him to basically see if the top of the rudder head moved when applying pressure and I was informed it was solid.
Another manufacturer makes the rudders for Hunter. Hunter for added protection adds white barrier coats. What was cracking and coming off was the white barrier coat with no noticable cracks in the underlying gel coat. I have seen this in the past and barrier coat although good is not needed at the head of the rudder and in the rudder cage, what you see is barrier coat coming off.
