There ARE people who would send off for a sheet of stainless feeler
stock, and cut a rectangle to wrap the rudder post with the smallest
possible weeper gap in the seal section, and having filled the sealing
area pits with loaded epoxy, would glue the wrapper round it.

On my old Cal-34 I used to wrap the rudder post with a layer or two of
heavy duty mylar sheet, goop it all up with water pump grease and
reinstall. It was usually good for a couple of years.
