He's not wrong, he's just not all-inclusive. When I posted the Cabot
link/info, I didn't say that they were the ONLY supplier, it's just they
are among the better-known. And it's not just that particular product,
nor must it be from Cabot ("Cab-O-Sil" line), it is, generically,
_hydrophobic_ fumed silica. Try searching/asking for that rather than a
particular Cabot product. There will be sources of it in smaller
quantities.
