I've a cast iron keel that has been rusting quietly under my boat for
the last few years. Most of the antifouling paint on the keel is on

A needle/descaling gun will do the job well. You can probably hire one,
but
don't forget the ear defenders


and a fairly hefty compressor - a needle gun uses a surprising amount of
air
if you use it continuously.

A Hilti TE104 is an electric needle gun, works very well.....
