Speaking of corrosion, just wait until you need to remove the brake rotors someday. I installed Rotex pads last year and pulled the rotors to have them turned. One of the rotors was rusted to the flange and I had a heck of a time removing it, and this was on a car that had only 10k miles at the time.

I used never-seize on the mating surfaces when I put the rotors back on to hopefully make things easier next time. I also use a light coating of never-seize on the mounting flanges of all my aluminum wheels. It really seems to help.
