Rotor rust
So at the end of the summer I bought some new brakes, calipers and roters. Was in dire need of breaks and rotors. I bought some AC Delco Cross Drilled rotors. I didn't know at the time the problem they had with rust. After about the 3rd car wash (by hand) I noticed the hats and outside edges of teh rotors had rust on them. The rotor itself did too but that disappears fast with one quick stop.
So now I'm trying to figure out what to do. Since the rust is there.
Any ideas?

You can take them off of the car and have them zinc dipped. There is probably a local place that does this. I also put new rotors on my car last year, mine were zinc coated and there is not a hint of rust on my rotors. Mine are Baer Rotors.

Your best bet is "zinc" coated in the future, but since you've already made your purchase, you could try what 'jrprich' suggested. Good luck...

I used a rust remover, then painted the outside rim of the rotor and put paint in the drilled holes. Then put chrome rotor hats on. (hats not on in photo)

I rust treated the crap out of mine and then painted them with rust proof paint. Almost 6 months and a thousand washes later, no signs of rust except where the brake shoes ride after a wash. As you stated, that disappears after the first stop. Notice how thick the paint is on the edges. I gunked it on real heavy so that no rust would ever show up there again.

Clean with brake cleaner. Paint them with high heat (1200 F) Rusteolum Paint. I used silver/aluminum. Paint the top hats (tape lugs), disk edge (no need to mask), holes, and vents (edges). Did several years ago, still good.

I care cause it really looks bad with my yellow calipers and thin spoke rims to see rust on there. Soon as it warms up a little. I'll pull the rotors off the car and use some rust remover and paint them with high temp paint.

Actually, you'd be much better off with cadmium-plated rotors.
Zinc is a very soft metal and at the thickness typically applied, is fairly flimsy in the long run. cadmium is much harder and more durable, even compared to an epoxy-based paint.
All PowerSlot rotors are cadmium-plated. Yes, they are more expensive than zinc-washed rotors, but the cad-plated rotors will look good far longer.

How could you not care? If you have to ask why then I would ask you "why do you drive a corvette?". If you dont care about the looks of your ride then drive a Pinto. For many (most) Corvette owners - looks are everything on our cars. Not trying to be a smart@ss but I was kinda shock that you even asked that question. 
Or perhaps you wanted this type of reaction?

I too went the Delco route for d&s rotors about 6 months ago. it didn't take long for them to look like crap. mostly hidden by the wagons I lived with it but I knew when I decided to switch to C6 wheels all that rust would show. I got the unfinished hats from Ecklers and painted them high temp black and painted the edges with Bill Hirsh's cast iron exhaust manifold paint. while at it I painted the calipers black also. the holes and slots are still rusty but the pad dust usually covers it. to do over I'd go plated....... live and learn
