Ken,

I may have mentioned this at Charlie's fly-in, but here is another method. SOMEONE, (forgive me if it was on this list) suggested that I try Hobb's #9 gun cleaner from Walmart. Just soak the plug ends for a couple of hours, and the lead melts off. No need to blast with beads and rough up the insulator. The stuff only costs a couple of bucks. I have no hard data yet, but have cleaned some old plugs to try.
