Kitfox Pilot brought up the time honored question regarding mixing flox in epoxy (IAW the instruction manual) to thicken it in a recent post. I didn't want to hijack his thread so I'm starting this one.

I'm assuming he was talking about the Hysol or Loctite 9460 that comes in the kit. If that is the case, then the question is: did you add flox (or anything) to thicken it? I didn't because mine didn't show any tendency go anywhere. The data sheet says it is 5 -10% fumed silica and that should be enough to give it the property we're looking for and the first "specific benefit" listed on the TDS is "non-sag slump resistance". Is there any chance that the instructions haven't caught up to the material in the new kits? If you have the time to respond - what is/was your experience?
