Ohhhhhhh........I thought ther was hope.
I too feel your (and others') pain, paid $2,000 for a Brenham slab that was
beautiful and now is is a bunch of space jewels that will one day be sent to
Twink---for a necklace and bracelet-etc..
Some people get lucky in their purchase and others not. Original condition
and subsequent preparation/preservation seems to be the key + Luck.
"Avoid rusters at all costs" === very subjective !!
What I can't seem to avoid, at all costs, is the impulse to respond to
ongoing, ongoing, continuing posts where the poster is in essence
just enjoying reading his own posts. Got it Adam..
Any further Information (Not Rhetoric) by anyone would be appreciated.
Just my $2,000 worth,

The fact that dealers are applying sealants and anti-rust coatings to
this Pallasite, like an old 55 Chevy from the East Coast, indicates that
Sericho (Habaswein) is indeed a ruster. I received several reports
today of rusticles, green goo, chemical smells, dislodged crystals and
popping noises coming from specimens. Maybe it should be upgraded from
ruster to serious ruster.
Stable Pallasites like Esquel do not require any special treatment other
than avoiding chlorinated water during preparation, proper high-grade
polishing and low humidity storage/display.
I avoid rusters at all costs,
