order coloidal silica

[Farrell]

The West System web page is: http://www.westsystem.com/  Click on "products"
and you will get a display of all their products as well as the various
fillers they offer. Good explanations of the filler uses and properties are
also provided. The filler I find myself most often using is their 404
High-Density Filler. But I keep about four different filler additives and
three different hardeners for various uses. Great stuff. One thing though -
get the mini pumps and use them. The only time you will potentially be
disappointed with their products is when you do not get the correct
proportions of resin and hardener mixed together. If you get that right, and
mix well, it works perfect every time!
