Jeremiah, there are a number of "restoration" threads on DP's here at GJ. If you follow a couple, there is a LOT of great advise on how to get stunning results, and many have finished up with DP's looking even BETTER than when brand new.
Assuming you completely disassemble (I recommend it) as an example the column shaft can be supported on a couple of rag lined cradles, (one guy used jack stands) and spun slowly with a variable speed drill motor using an oil filter wench and a 3/8 extension and two universals (to get a constant velocity U joint out of it)
They used crocus cloth or fine wet/dry and the collumns were stunning.
Another guy polished the aluminum bits to a mirror finish ( stay away from the "machined" top decorative strip however!)
De-rusting and painting sort of goes without saying.
You do that sort of job, and show her the "before and after" and I'd bet she will be more than impressed!
