The archives are replete <G> with this, just not recently. First, Wim's 
right. Fix=replace. The only wrong way to do it that I found worth the 
time was a thorough soaking with the silicone and naphtha mix, heated in 
with a heat gun until it bubbled up and smoked, darkening the flanges 
and scaring the bejeebers out of the operator. Two consecutive 
applications. Lasted about six years before the centers started seizing 
again. I have no idea how many brain cells it killed... but then I 
wouldn't, would I?
