I did exactly what Dave recommends here- I cleaned up the joint with a dremel, laid two or three strips of glass, sanded it smooth, and painted over it with two part gel-coat. It seems to be holding up well after a few years, however the job killed my cheap cordless dremel. I'm not too worried about the steel ballast anymore as it should stay dry now. It would have been a quick and easy job if I hadn't put an 8" long hole deep up inside the trunk trying to hammer the stuck centerboard down from the top with a steel rod.

If that entire joint is not weeping rust you likely have no issue with the keel ballast.
That joint was just filled with thickened resin. Not hard to grind it out with a dremel to get a rough surface and then lay and some fiberglass, then thickened resin, and then cover over with some fiberglass. Sand smooth. Paint over with your coat.
For the fiberglass work late in some mat, and then cloth, not just cloth as will pop off.
Somewhere I think I have pictures of this repair being done. I'll look for photos when I get back to Golden.
