Rust spots on rotors
OK, I'm a bit of a newb and not sure if this is something to be very concerned about, but the other day I noticed all 4 of my rotors were pockmarked with huge, bright red rust spots.
I drove home on a rainy night and the car sat for over 24 hours over the weekend (I was sick). The day after that, I came out and all of a sudden, my brake rotors were covered in a coating of rust. Yikes! After driving for a while, I determined that brake function was normal and not affected, and the rust spots quickly disappeared...the rotors were once again shiny.
Have others noticed the same thing? Are the rust spots an indication of a problem? I am concerned because I don't have a garage where I live and the car will be sitting exposed to all the elements (hence my decision to rustproof it). I know the rust came from the car sitting after it rained...and it looks like the rotors will rust again after the next rain, causing a cycle of superficial rusting.
Will this prematurely destroy the brake rotors? What measures can I take to prevent more rust? Or am I just nuts?

It's OK, it happens to all of us. Just take it around for a spin and it will be nice and shiny again. 
I suppose if it really bothers you, you can switch it out with a better rotor made with a different material.

Good! Now I can sleep at night! Just kiddin'...
You know how it is when you have a nice newer car--any little thing seemingly out of place disturbs you. You should've heard me curse when I accidentally drove over a curb in a badly-lit parking garage last week. People could probably hear me for miles.

Yeah, I know what you mean. I was upset too when I bought my car brand new only to see rust on my rotors after a few days. It was the guys in here who informed me that it was normal. If you ever go to a car dealership, check out the Mustangs and you will notice the rust build up on the rotors from sitting on the lot.
