Rust on Rotors

I’m very disappointed with my new Mopar Front Brake Rotors that my dealer installed to replace the original brake rotors that were on my van since new. Within a week, the hub portion and edges of the ventilation fins had developed a bright orange layer of rust. The service manager says it is “normal” and there is nothing they can do. My original rotors never did this and that is why I had the dealer do the work, so I would get factory parts. Now I find that all rotors are not the same. Some have anti corrosion coatings which would prevent this unsightly issue.
im considering replacing the brake rotors myself with a better brand. Soooo disappointed! Any suggestions on a better aftermarket replacement rotor?

That is normal. My OEM factory rotors look the same. BTW all rotors in boxes come with anti-corrosion rosin coatings that have to be cleaned off the brake pad contact surfaces before installation. The rest of the rosin coating will burn off with heat. You could buy a set of rotors and have the non-contact brake pad areas powder coated it if bothers you.

Clean new brake rotors
I guess my assumptions were wrong.. I always thought dealers used OEM parts.. hence how expensive they always are. If they are using cheap parts and they are expensive I guess you are only paying for the "experienced" mechanic? I put that in quotes because I've seen a few "experienced" mechanics in my life and I've seen others who truly are 100% legit amazing mechanics. Paying for real experience is 100% worth it but paying for part changers is generally not..
On many occasions while at my dealer for software updates or oil changes I have seen Auto Zone, Napa Auto, and & O'Reilly's Auto Parts drivers pulling into the service area and dropping off ordered parts.

I think this is tacky to do this as I would only want OEM parts on my vehicle being replaced at a dealer. If I wanted aftermarket I would go to a local jake of all trades shop.
