I must be abnormal, then... <fx: glowers at the UKRM multitude> ....though those who saw my Guzzi at the EOSM mught possibly guess that it doesn't get washed that often. Or polished, repainted or, in fact, any cosmetic work done at all. Actually, they'd guess wrong, but it is a low priority. From what you're saying, copper grease on steel/aluminium interfaces only works because of the grease? I have to say that I've never had a problem with copper grease on aluminium/iron. The grease does turn black, so the copper seems to get involved in some way. Is it possible that it somehow prevents the oxide mix from forming a nasty solid interlocking cement? IME, iron/aluminium ends up producing a rust/aluminium oxide mix that swells and can in extreme cases burst an Al casting (the Al collars on my Guzzi's alternator actually broke into pieces due to contact with the iron stator, though maybe eddy currents helped) -- -Pip
