Hi Lee,
For all the fiberglass work and bonding I'm using the West System Epoxy Resin. For the vinyl ester fiberglass work I'm mixing the 105 epoxy resin with the 205 fast cure hardener. When bonding (including the light rings) I mix in the 404 high-density filler. Per the West Systems pamphlet, "The 404 is a thickening additive developed for max physical properties in hardware bonding. It can also be used for filleting and gap-filling where maximum strength is necessary."
This stuff is fun to work with but you have to work quickly since it will "kick-off" before you know it. I would recommend using the 206 slow-cure hardener to give you more time.
