Thanks David. I found the specs for 406 and see that
it is a colloidal silica thats to be added to regular
gel coat. They claim that it is off-white in color.
When mixed with gel coat does it color match an unweathered
glider finish and will it accept a polish?
Thanks!

I there a way to thicken gel coat other than letting
some of the solvent evaporate? Even the thinnest
commerical
gel coat is made for spraying which makes it too
runny
for filling small cometic chips. The only gel coat
paste fillers I have found are an off white in color.

Plastics shops sell colloidal silica filler, which
you can mix in
the gel coat before adding the catalyst. It's white,
and a whole
lot safer than microballoons, which can waft into
your lungs
and do real nasty things.


If you get the West System filler, the 406 is pure
white, but the 407
is a purple color.
