I think the name of it is Naval Jelly. It's a gooey substance that you brush on, let it sit and wash it off. Once something is cleaned with it it is slow to re-oxidize. Get her clean, then a little Zinc Chromate primer (auto paint stores usually carry it in a spray) and top off with Merc Phantom Black Lacquer.

Also, after you remove the rust/corrosion back to the clean, base metal, for tight areas you can spray your primer/paint onto a Q-Tip and apply it that way to prevent overspray from getting all over. After you get it all clean, primed and painted, let it dry real good and spray the area with white Lithium Grease to make a great waterproof protective coating. Good Luck!
