Leave it alone. Its a beauty. Always keep in mind that it is only original once. You can not ever have its true character back once restored or refinished. I would advise against the clear coat though, I would imagine it would begin flaking off due to the rust continuing to do its thing. That type of rust is not bad, Its only surface. When you decide restore it fine but until you are ready to pull the trigger on it, leave its story showing. Mine is a lot like it but a 56'. You'll get more compliments than you can imagine.
