A million guys, a million opinions - and they're ALL probably right in one way or another. Just for giggles, here's mine: Just over the past winter I built/rebuilt/restored 4 planes, 1 was over 40 years old and had just come apart in front, the other 3 were just crashed bits & pieces of old planes. All are in the air again and doing just fine. Glues came from Lowes, Hobby Lobby, Wallyworld and my local hardware store - no LHS anywhere close to me. For the most part, Devcon 12-hr or 5-minute from my local hardware store got the nod (and always does) for where I needed epoxy and regular glue duties was handled by Titebond-II from Lowes or my decades-old standby, Duco cement, from my local hardware store. Yeah, it's ancient but it still works just wonderfully as long as you work it properly (gussets, etc). Loctite "Professional" (LOL, that's the name, not the "quality") CA from wallyworld got the job done just fine where I used CA.
I, personally, don't know or trust Gorilla anything enough to put it in a plane.
But, this is all just me.
