But I personally dont like the white powder in the Cab-o-sil tub, or understand it as well as i understand the wood flour, so I only use wood flour in my boats.

I seem to remember reading somewhere that epoxy paste mixed with cab-o-sil is more brittle than if mixed with wood flour, hardening my prejudice against the white stuff.

: John, Not sure if its my place or not, since I'm pretty new at all this, but
: I hope you meant (epoxy/cab-o-sil paste). Its my understanding cab-o-sil
: or silica is meant for glueing and wood flour is meant for filling and or
: filleting.
