Score High Gunsmithing Fumed Silica 1 Pint
The best method of thickening epoxy by far is through the use of Fumed Silica. There are times when bedding a stock that you need the epoxy to stay exactly where you put it. Fumed silica can be added to Pro-Bed 2000 to such an extent to make the epoxy as thick as dough with absolutely no negative effects on the finished product. The thixotropic properties of the Fumed Silica allow for ease of mixing with the epoxy.
