  Verne: 
  I came in on this thread late.  Where do you get Cabosil?  It sounds like something I could use for a current repair on a glass fuselage.  Thanks.

    Cabosil is fumed silica sand. It's extremely light weight. When mixed with epoxy finishing resin, it creates a paste that won't run on vertical surfaces. It's also frequently mixed with epoxy in a thinner mix and brushed into a mold to create the external gel coat on a glass part which prevents pinholes from making it to the surface of a part. On a clear epoxy-cloth piece, the epoxy/cabosil mix can be seen in all the 90-degree corners to bridge the radius the cloth can't make. It'll show as an opaque white as opposed to the clear epoxy/cloth you see everywhere else. Down side is that it's much tougher to sand than micro-balloons and has virtually no structural strength. Good stuff to have around, though. I use it a lot. Verne
