What's the best, most durable procedure to follow here? I'd be
interested in professional help (New Jersey). Also, Is there anyone
who manufactures custom replacement keels that do not contain iron?

Thanks in advance,

I had a Tanzer 22 that had a cast iron keel, and tried several approaches
before finding the right approach that lasted over 15 years with only a
minor touch up every so often. The problem with cast iron keels is that
you need to put a serious epoxy layer over it once it has been sandblasted
clean to seal and protect it from the sal****er and copper-based antifouling
paint.

Interlux sells their Interprotect 2000e/2001e product that works well in
this application. They have a web site (www.yachtpaint.com) that gives
details on the procedure to protect cast iron keels. Take a look at
http://www.yachtpaint.com/USA/boat_p...ng/running.pdf

Note that you need to start covering the newly sandblasted keel almost
immediately. Also, pay attention to the Interprotect re-coating times so
that you can put additional coats on without having to sand the surface
between coats.

I used the optional primer wash step as my first coat.

Good luck - it is a rewarding project.
