A great gun oil to use is G96. Unlike many of the others it does not have the odor many have and it leaves less of an oily feeling on the meteorite. Not too easy to find but Google it to find mail order suppliers.

Maybe the mineral dealers from China can start using it. Too often their specimens are so heavily oiled that you're afraid they will slip out of your hands if you pick them up.
