The way I see it is there are two issues with rusting:


1) water/chlorine oxygen that is in the meteorite when you buy it, Often
due to etching in water based etchants or rain damage when it was in the
ground - This causes rusting even if you coat it in varnish since it is
just using up contaminants inside the matrix. To over come this type of
rusting you need to dry the metal very well and maybe even use sodium
hydroxide solution to neutralize any acid.

2) External sources of water vapor, chlorine and such: This can be
prevented by using appropriate VCI and dessicant or dehumidification and
keeping the specimens in a closed cabinet away from draughts and sources
of water or contaminats. And this means not using bear fingers when you
pick up irons!


Some Irons do seem to rust no matter what you do to them, but I have
succsfully stabilized 6 kilos of campo and it is as fresh as the day it
was cut over a year on.

The best stuff I have found is 'Lithium Grease', just spread a smear on
iron slices all over on and then wipe off the excess it protects for at
least 6 months...

Dear, I give up rusters. I'm perplexed at the people who have given up!
        Why can I solve the problem of continued corrosion and you
can't?
I'm not magic and I can understand the cause of corrosion. Why doesn't
anybody start thinking what causes rust? OPEN conversation invited!
