Re: Fillite Powder substitute
Actually, Cabosil is harder to sand. But if you add just a little
Cabosil (fumed silica) it makes the mix handle better. When working
with tape the real trick is to put it over the filler while it is
still wet.

with an acetone soaked cloth does most of the job and you can't beat
the price.

How about wood flour with a little bit of Cabosil (fumed silica).
Say about 1 part in 5. That's what I use with epoxy. Raka
(www.raka.com) and lots of other boat supply places have these. You
could use 100% fumed silica, but it would cost you more and be harder
to sand. Other people use anything from powdered limestone to
diatamaceous (sp?) earth from the pool suppy place, to real flour (the
kind you can eat. Having no experience with those, I can't say how
they work. Wood flour and fumed silica seem to work quite well.

'Build the New Instant Boats' lists Fillite as a resin thickener. I
cannot find this product through an internet search, so I assume it is
no longer available. What would be a (cheap) substitute?
