For those of you in drier climates this may not be a problem, for the rest of us here goes... I have noticed rust on the outer edge of the rear disk brakes and on the inner edge near the hub, it looks bad! The rust is on the unfinished portion of the brake disc and not on the braking surface itself. I have decided that I will be taking a wire brush to the rusted surfaces, cleaning the rust off and coating the surfaces with hi-temp primer and probably hi-temp flat black paint to match the rest of the disc. I will apply the paint with a small detail brush since the rough surface will not show brush strokes very well, this in lieu of spray painting them. Any others see this, come up with any ideas yet?
