I have gone to West epoxy for everything. I use the Small Batch epoxy scale for small quantities.

I use West system 105 epoxy resin and several west system hardeners listed below depending on application

Fast - 205
Slow - 206
Special coating - 207
Extra slow - 209


I also use their fillers

410 Microlight filler for fairing
404 High -denisity

A good place to get this stuff is www.jamestowndistributors.com

I also use Plexus MA310 for plastic to anything bonding. Works well in my model sailboats that are made of styrene.
