Did you use brake cleaner on the rotors? If so, then it probably is rust. if not, then its the brake dust settling onto that area. I used brake cleaner on mine, unfotunately, and its rusted over on the untouched area.

It is normal for the rotors to rust. Any mild steel will rust immediatley. I run into it all the time @ work. When i steam clean steel parts unless i get an air hose & blow it off immediatley rust will show up in 10 min. or less. Too bad they didn't make stainless steel rotors. Would never see rust with that material.

same problem, I put on my Rotora Slotted 4 weeks ago and they hub part started 'rusting' but i dont mind, since its not THAT noticeable, but would like to paint that part black as the same as njzprettyboy did.
One question, can the brake cleaner break the rust off of those areas?

I used CRC break cleaner on my power slots when I installed them and have not had any rust after a few months of them being on. Might be because I am in vegas too I imagine people in humid climates probably have real problems with this but my OEM rotors I left in the rears have rusted pretty bad. I think I got em that way though.

It is called oxidation and it happens to ALL rotors.. After washing a car it will happen, condensation will cause it. Water will sit on the rotor and turn it a goldish/brown. Once you apply the brakes the pad will burn it off, but only where the pad touches. There is still part of the rotor that is untouched. If you sprayed brake cleaner on the rotor then you basically wiped off the protective coating on there and now oxidation will build up. Oxidation will eventually turn into rust if left untouched. Look at your OEM rotors, they will have rust in the vanes and right above the hub area. The rotor will still last 75K plus. However, the thin line of oxidation is unsightly to some so you could sand it down/clean it off and then spray paint it with a high temp black paint, but it's such a small line though.

I agree. Since rotors are pretty much bare metal, except for zinc coated "hats" on some, unless you're in a very dry climate,the oxidation is inevitable. Since new, I always brush on a coat of black rust paint (Rust-O-Leum $5.00 from Wally mart) using a narrow brush for the outer and vented part and medium wide brush for the hub part. Make sure you scrub with a steel brush before painting. I do this everytime I mount back the summer rims and saves me the job of lifting the car again.
I recently replaced the front rotors and before installation, spray painted these parts with black (same) paint and masked the contact areas. Make sure to use flat or semi-gloss as flat black will dull out and turn to an ugly gray.

Painitng hubs (OEM)
So, it is ok to paint the hub portion of the rotor? I've heard conflicting stories - as some say it is ok and some say don't do it. My OEM hubs are rusted and it looks unsightly, especially now after I installed my new rims, you can see them more directly.
Would coating them with a high-temp paint do the trick?

"Too bad they didn't make stainless steel rotors. Would never see rust with that material."
SS is still a ferrous material and can/will rust if the surface gets a scratch down past the chromium coating.
If you're concerned with rust on the hub then look into this product:
www.por15.com
as long as their no clearance issues nothing wrong with painting hubs.

Hey special e. dition,
What type/brand of paint did you use on your calipers/hubs? I know there are many out there to choose form, just curious as to what you used.

Another idea is to apply anti-seize on the bolts prior to tightening the lugs. Just suggestions.
