Glass strands (various lengths from milled fibres to chopped strands)- hard to fair but strong - structural. Fumed silica - cab-o-sil - this is a colloidal filler, it keeps the epoxy from flowing. This is not the same thing as making it 'thicker' - glass will do that, but without silica, the reain can still run, fillers can still sag. You need silica to make putty. The stiffness of the mix will vary - is this for coating, laminating, adhesion with gap filling, fairing, structural filling? Micro balloons - fillers with various degrees of fair-ability. Different materials. Talc - cheap-ass filler used in bondo and 'cow flap' polyester used in our c&cs.
Peel ply - a nylon material that is porous to epoxy that can be lifted off after cure. Leaves a finished surface. (More significant in vaccum bagging). Nylon taffeta from the fabric store works. Acetone can be used on a cloth to help shape 'b stage' epoxy. Isopropyl alcohol for clean up (a challenge) Waxed paper or 'tack tape' works as a release. I welcome critiques or additions.... Lots of good info on the gougeon site and many others . Great stuff to experiment with.
