[RocketsNW] Sticky Fillets??

[Carl Degner]

I don't know about TAP but West Systems (and the Proline which Wildman is
not selling) epoxy is supposed to be mixed at ~5 parts resin: 1 part
hardener (not 4:1) for the 205 or 206 hardeners and ~3.5:1 for the 207 and
209 hardeners (which do not really have any good uses for building rockets).
