Scroll about half-way down and click on "Filler Buying Guide" - it details how much of the various fillers is need= ed to achieve catsup, mayonnaise, and peanut butter consistencies. Often, in situations like filling a rib notch where strength is simply not a concern= , I will use #407 Low-Density filler (microballons) because it is so incredibly easy to sand.</DIV> <DIV> </DIV> <DIV>When using epoxy to bond things that require a high strength bond (li= ke a wooden rim brace, fish or cut-off bar), I almost always use #404 High-Dens= ity filler. Mmmmm heap strong stuff!</DIV> <DIV> </DIV> <DIV>Another West System filler that I always keep on my shelf is #403 Microfibers. I always use that for laminating structural elements such as laminated cut-off bars, bridge roots and caps, and pinblocks.</DIV> <DIV> </DIV> <DIV>On the West System website, right next to where you can click on "Fil= ler Buying Guide" is "Filler Selection Guide" - that outlines the most common recommended uses and properties of the various fillers.</DIV> <DIV> </DIV> <DIV>I don't really use the colloidal silica because there are other bette= r fillers for situations I run across and because it is more difficult to mi= x into the resin than other fillers.</DIV> <DIV> </DIV> <DIV>Terry Farrell</DIV></FONT></BLOCKQUOTE></DIV> <DIV></DIV> <DIV> </DIV></FONT></BODY></HTML>
