My MSD Cap failed after a few hundred miles...this was before I heard of the rotor contact not making contact with the carbon button. The button itself fell off but it did not disinegrate. When replaced I bent the rotor up and have not experienced any issues and have close to 5000 miles. I bend it up a few times a season to be on the safe side. I remember the arching did create a whole bunch of rust inside the cap.
