RE: epoxy HELP
It sounds as if the resin was not mixed properly. If this is the case prepare yourself for the worst.
The following sometimes works but there are no guarantees.
Try applying heat with a heat gun.
Wait for a month.
Scrape off as much as you can and apply a coat of correctly mixed resin over the top.
As far as wrecking the aircraft, it is already done. So you may have to take it apart and start over.
