RE: gorilla glue vs. epoxy
I wil say there is the best glue dependig the aplication.
Gorilla makes lite bonds to foam penetrating and filling voids.
Epoxy is heavy and makes strong bonds where vibration is an issue.
CA or instant glue is fast but britle.
White glue is a very good all pupose glue but very slow gluing.
So with experience and experimentarion you will find the best suited glue for the job.
In my contry gorrilla glue has a very short shelf life to to hi humidity.
