How do you fair a keel?
I have a 1964 Rainbow 24 with a cast iron bulb keel. I''m in the process of removing all the old cracked fairing compound and then I plan on sandblasting the bare metal. I have read a number of posts regarding rust converters and epoxy primers,etc.. So, I have a good idea how to prep and cover the surface. But, I''m sort of confused on exactly how to go about "fairing" the keel. Or, do I really need to fair? Can anyone enlighten me? Thanks.
