Setting finboxes and adding thickner to the epoxy

Hi people, need some advice again please!

About to set the finboxes with Resin Research Kwik Kick and I read or saw somewhere which recommends adding this stuff to the epoxy - http://www.seabase.eu/product/MFS/Seabase/Coatings-:AND:-Sealants/Ceramic-

Is this in fact the same stuff as Cab-O-Sil?

I can't for the life of me find the link or tutorial with information as to how much thickner to add to the epoxy for setting finboxes (and leash plugs I suppose), can anyone recommend the thickner to epoxy ratio please?

Also - is Additive F recommended at this stage? And if so, how much?

Cheers :-)
