Cab-O-Sil, Aer-O-Sil, etc are powdered thickening agents primarially
used with epoxy.
Small quantites are available thru anybody that sells epoxy resin.
A 1lb can will probably be good for a lifetime for the typical wood
worker.

Micro-balloons and Cab-O-Sil (Fumed Silica) are diffent products.
Fumed Silica is an isentropic thickener while micro-balloons are a
filler of which there are at least two (2) types.
Phenolic (brown/purple) which are very light weight and very expensive
and a more generic (white) which are very low cost.

They are made of phenolic resin. Resultant mix using them is red
(dark).

Pumice is white but turns translucent (not completely transparent) when
mix with shellac. It's used as a pore filler in "french polishing". I
recommend "FFFF" pumice.
All the rottenstone I've seen if black in color. I don't think it would
work.

Similar stuff is sold in r/c hobby shops (and online) in small
quantities as "micro ballons".

That would fill but neither pumice or rottenstone are transparent.
Lacquer works as a vehicle too. Cab-o-sil is fumed silica...it is
*extremely* fine and is often used as a thickener for epoxy or
polyester resin. Same purpose in paints too IIRC.

Confirmed. That transparent oil base filler exists. Heck, you can
even make your own with some cabosil and varnish. The commercial
generally has relatively little resin and is mostly thinned with
naptha so it will dry rapidly.

Well, I've been reading Flexner's finishing book and he seems to imply
that the oil-based pore fillers you either color or put down in a
neutral color. He does clearly say, however, that water-based pore
fillers come in transparent. So I was just looking for some
confirmation.

Cab-o-sil and microballoons are different products serving different
purposes. Manufacturers of microballoons suggest adding cabosil to
control floatation of the balloons in low-density resins for example.
Microballoons come in phenolic or glass.
In the given application I'd try cabosil and I'd try glass
microballoons and see which worked better.

It's all as you see in the store, the minwax site, moore's site, etc etc

Don't know what cabosil is, but I seem to remember reading that you could
make a good pore filler by mixing pumice or rottenstone with shellac.
