Hi. I talked to John Pirkle about that very topic. The problem is, caps live in a relatively volatile environment. He claims he stopped restoring them because the vast majority of cores were thin or unusable in the area near the rivet. The fix was to weld them, and that was something he decided he didn't want to do. The cause was corrosion. Makes sense I think. Particularly when you factor in the age (mileage I don't believe enters the equation).

Just my two bits. [img]<<GRAEMLIN_URL>>/smile.gif[/img]
