If you want a truly durable surface, a clear powdercoat done within a short time after the frame has been final-prepped (sanding, Scotchbrite brushing, polishing wheel or media-blasting are all possibilities depending on the look you're after) would be the best option.
However, I had the Casati media-blasted, then I went over it a bit with some 00 Scotchbrite pads. Finally, I shot Krylon matte (flat) clear and it gives a nice, even finish. It's not anywhere near as durable as PC, or even a urethane clear, but since you're not planning on it seeing rain and keeping it indoors, well, it should be fine. I have a couple rust blooms after over the past year (refinished last summer), but they are small - not much bigger than the small blemishes you posted in your pics - the same aesthetic you like.
