I have a 94' Hunter 26. I have some bubbling of the paint on the plates on each side of the rudder. Some of the bubbling is at the foot and around the bolt holes. I had to take the tiller home to refinish and figured I would fix the coating on the rudder plates. The question is can I just sand down the surface and paint with an epoxy based paint. Or should I take the whole surface back to metal or aluminum and have it powder coated. The damage was there when I bought the boat a few years back and did think much about it until now. I think the problem was caused by the boat sitting in salt water for the first eight years of its life and dissimilar metals. I can post a picture if someone has any ideas and wants to see the corrosion. Carl
