I've got a selection of stuff from Eastwood to take care of the paint angle -- Metal Wash, Rust Converter Kit, Rust Encapsulator, and Chassis Black. It's getting rid of the rust in the joints that will be the biggest task. That's why in another thread I was asking about replacing rivets with bolts (which it appears could be a very costly option).
Oven cleaner and power washer ... have to give that a try. Never even thought about the rarely used Karcher hiding in the basement! Out of sight, out of mind. That could help with the crevices.
