You could also just strip the paint and go with the raw look and a layer of clear coat. No paint to touch up and easy rust removal.

If you're looking to stay ahead of the rust, check your steerer tube. After 20,000 miles of 4 season riding, mine is pretty rusty.

But, that bike is also getting re-built over the course of the next month. I'm thinking about stripping it for the winter and leaving the raw look for at least the winter commute season.
