Mountain Biking - Maintenance tips for a steel frame?

Does anyone have any tips for preventing rust and keeping a steel frame in top condition? My frame is relatively new (two years old) and in pretty good shape, but it's beginning to get somewhat chipped on the down tube and bottom bracket. From the looks of things, the chips aren't down to bare metal, but they seem to have taken off the shiny top coat of paint. These are all tiny little specks from rocks being thrown up, much like you find on a car's hood after a lot of highway driving. I figure my best bet is to clean the tube really well and then dab clear nail polish on the spots, but this won't leave a very smooth finish. Any better ideas?

Two tips:

Car wax frequently

Use silicone dry lube spray lightly on frame, prevents crud from sticking. Don't get it near brakes/rims/tires.

There is a product called "Frame Saver" that you spray on the INSIDE of your tubes. This prevents oxidation (or is it corrosion) of your frame.

As far as chips, it's a moutain bike. Chips in paint are like scars on your body. Each one tells a story (or gets a great story made up) and plus, chick dig em.

Oh yeah, forgot to mention, there is a product that 3M makes that is a clear film that is used on the fronts of cars that acts as a protectant/deflector. Maybe an automotive specialty parts supplier can get it for you in rolled goods???

Thanks for the tip. I'm not worried about the chips from a cosmetic point of view, but if the chips lead to rust I won't be a happy camper.
