rust is on the inside of the wheel, mostly on the rear and visible when looking at the inside of the rim. Does anyone know if Acura is fixing this with some "rustproofing?"

 

When you say 'inside of the wheel' do you mean the disc?

 

its on the rotor

 

Well, I hate to tell you this, but rotors rust.

If the rust is on the face of the rotor, where the pad touches, it will wear off after the first couple of stops on your next time out.

If there is rust on other parts of the rotor, then sorry thats what happens to bare metal when it gets wet. You can buy new rotors that are cadmium plated or zinc anodized. This gives the rotors a sort of gold hue to them. The cadmium/zinc wears off the face, but remains on the rest of the rotor, protecting it from rust.

Here is a pic of zinc anodized ebc rotors:

 

Yes, while rotating my tires last time, I found out the same rust effects inside the rims. And, the rotors and brakes are definitely like that, too. (I'm still whining my rust tips... :o)
