There are way cheaper and probably better sources of super glue than that stuff.
For super glues I like these people:
Good products decent prices and they are always willing to offer technical advice.
However as a general woodworking glue super glues are not the best. They definitely have their uses but as an all around super duty glue Good old Titebond is better than anything I've ever heard of or used. OT's better than epoxy, flexible so it's got advantages over resourcinol, I think it's way stronger than plastic resin glue, and hot glues.
Titebond. It's the shizz
If you mean gorilla glue treat that crap like the worthless garbage that it is.
Gorilla glue was invented as a glue for hot tropical teak and IPE wood assembly where humidity is so high it interferes with most glues. The stuff actually benefits from the moisture. However in that application it was ultimately a failure. It was a failure because the stuff is not strong, doesn't establish a very good bond with wood, and the joints fail along the glueline well before the wood substrate does.
But Marketing (the scum of the earth) was not going to waste all those R&D dollars and just shelve it. NO-SIREE_U_BOB they put themselves together a pack of falsehoods (commonly known as howling bald faced lies), fancy claims, a groovy package and sold it to us.
If you want very strong joints with no fasteners showing AND can tolerate some internal structure you can square up some 2-by stock and use that inside the corners and even screw through it to the ply - just don't use screws that are so long they pierce the outside.
