I bought a large bag (probably enough to fill 100s of containers) for

says that it is an agent they use in fiberglass construction. He used
to build custom airplanes and had used it in the past. Hopefully
he'll comment on this. It is definitely NOT silica gel

Willi,

I'm pretty sure the Frog's Fanny is Cab-O-Sil. It looks like and
behaves
like it anyway. We used it to keep resin from flowing on vertical
surfaces. Someone who's experienced with how Frog's Fanny works should
order some and compare. It's really cheap. I'm sorry that I threw
the bag (1 gallon) away when I swore off fiberglassing.
Aircraft Spruce & Specialty in CA sells it. My old catalog has a
part no. of
01-14711 at a price of $2.85 for a gallon bag. This catalog is 1995
so don't know what the price might be now. The phone number for ACS
is 800-824-1930. Freight is probably more than the goods. Another
possible source would be West Marine. You'll have to figure out what
to use for a bottle and brush.

The different forms of silica are intereting to ... the colloidal one for
instance "... the silica particles must be small enough such that they
are largely unaffected by gravity." - sound familiar?
