Setting boxes with poly in epoxy laminated boards

Anyone do this in a production setting or if you just don’t want to wait for the epoxy to kick?
It’s seems a bit tedious to wait when you could be sanding by the time the epoxy starts to gel.
Or is there a particular epoxy product I should use in stead of the laminating epoxy?

Fiberglass Hawaii three minute epoxy.  Disregard the mixing instructions,  it needs to be 2 to 1 by volume or 10 to 4 by weight.  Fiberglass hawaii knows the label is wrong, but the haven’t changed it yet.
