It would be easy for people
So what use on different kinds of foams,  balsa, coro,etc.

I use rubber cement like fevibond bondfix or quickfix on coro to coro surface joints. And for coro to coro 90 degree joints i use feviquick.

And for foam to foam joints i find fevicol a lighter and stronger than hotglue though not quicker.

corro to corro- fevibond
90 degree corro to corro- fevibond; hot glue ; quickfix at equal spacings
foam to corro- hotglue
balsa- quickfix/ feviquick

Corro fevibond or feviquick thick(it's very hard to get one of these and these are actually medium not thick,  the shop from where I used to get one of these no more stocks them, so I just use a local CA and modify it to thick)
Hot glue for foam
Quickfix for balsa
And epoxy for carbon spars

Before anyone ask feviquick thick?  What?
It's like a fevibond tube smaller in size
And it doesn't say feviquick thick
Rather it  is (was) six months old and the ca that comes is thicker and I say (apologies) it's feviquick thick because from where I used to bought it sell it by the name feviquick thick and I have got used to it
Also I know spelling of feviquick is fevikwik

So how to modify a normal to thick. ?

well , its just the luck that you get the one which i have
it doesn't have any label
but you can turn it into thick by shaking it hardly till bubble are form
and open the cap
then put a roughed up ear bud and put it in
leave the the thing for a day or two in place deprived of any cold and sunlight
also it should not have much dust but a lot of air(you can use a fan for air)
if only the bubbles forms gets hard the ca will get very thick
BUT MIND THAT I HAVE TESTED THIS A HELL LOT OF CA(s) ONLY ONE OF THEM GETS THICK
OTHER JUST BECOMES HARD AS A BRICK

Balsa- Fevicol SpeedX(Takes about 1 hour) and QuickFix. Used to use CA, But have developed a wierd reaction to it(Runny Nose etc)
Coroplast: Hot Glue
Epoxy only when required.

For foam to foam I use Araldite Klear 5-Minute Epoxy. It works really well.
