Cab-o-Sil. Fumed silica. Available from aircraft and boat supply houses.
Got
mine from an outfit called Spruce Aircraft, IIRC.
Cost is about 12 bucks a gallon, which should be a lifetime supply.


I'm not convinced that fumed silica, as sold for thickening resins, IS the
same as Frog's Fanny.

I thought Frog's Fanny was similar to _hydrophobic_ (treated, oiled,
siliconed, etc.) fumed silica, not regular untreated. I have no idea
which "Cab-o-Sil" is being discussed, so ???. Then there are the toner
product-related types, too. IAC, unless you have the right/same fumed
silica, your mileage WILL vary.

Do a googling on "cabot degussa silica" and you'll probably find enough
to bore you to tears.
