Tim, Unfortunately for me, access to any of Mr. Nobel's stuff has never materialized. Otherwise I'd have used it on more than just stubborn dust-caps! No, for me it has always been the Zen-like transcendence of inner-peace to overcome the frustrating obstacles of everyday life. THEN, if all else fails, The Louieville Slugger! As Eastwood says, nothing beats a good piece of hickory. In all seriousness, I used a bit of rubberized shelve paper to coax the blighter off. Thanks again to all for the great suggestions. Doug
