Well to be honest the OP was asking what kind of glue to use as they didn't think what was supplied in the kit they purchased was suitable, not where to buy glue from.
Simply pointing them to the biggest manufacturer of adhesives in the world is hardly helpful advice. The amount of adhesive products that 3M sell is daunting and I doubt any of the literature on their site is loudspeaker-specific. Some of their literature is based on an assumed level of knowledge - for instance knowing that certain types of glue will dissolve certain types of foam. I'm all for being resourceful and trying to work things out myself from information that is already available but sometimes it is faster and easier to simply ask for others experience/advice before I dive into a project and make a mistake that others have already made. A useful reply would be "I used <adhesive brand and product number> to repair my speakers and it worked out great" or even "don't use aeroplane model glue, I did and it went bad"

Probably the advice to look at the "biggest adhesive manufacturers" is rather non-specific. However I am sure that they have adhesives that are spec'd for foam to metal bonding. That is ALL that is needed, a permanent bond for foam to metal/paint. The loudspeaker part is incidental. If ur unsure what sort of foam the surrounds are, that can be found pretty easily by a bit of internet searching. Afaik there have been only two types of foams used in modern times for surrounds. I'm sorry but since I don't deal with the composition of these foams often, I can't cite the two types. The newer is more stable, iirc. I've read about it a few times.
Btw, both companies do sell products specifically to the loudspeaker industry, so you might be surprised what comes up in their application advice.
All sorts of stuff has been suggested in various threads to do these jobs.
Including things that maybe shouldn't be used. Also things that are more likely than not
to fail in some time, sooner or later.
I did suggest to call around to some speaker recone shops and make a gentle inquiry. Most will not tell you much of anything, fwiw.
It would have been pretty simple, I expect, to have done a search on 3M's or Loctite/Henkel's sites and come up with a few likely candidates and then posted them here and asked if any of them might be suitable.
Both companies have local suppliers and almost anything you can think of in their product lines now seems to be sold somewhere online...
And, why not inquire back to the people who sold you the kit??
Also, while I did not look at the product, if Parts Express is now selling a bonding adhesive for foam to metal/paint, that's a sure bet. It might be for foam to paper/plastic cones only. Don't know.
So, what's the problem here?

Update: I used the airplane glue that came with the surrounds, and it wasn't a good experience. It was grabby, and I had a hard time centering the surrounds. I can't imagine people using contact cement getting things centered -- but maybe they don't get things centered.
I won't use it again. Bummer that this lousy outcome happened on a pair of expensive JBL woofers.

That's what you get from asking and getting good advice and ignoring it. A well deserved learning experience, I would say.
"Which advice was the good advice? "
The Weldbond advice, been using it for over 30 years now.

Speakerbits in Oz sells a great water based glue for surrounds, cones, spiders etc.

From what I have seen the OP has yet to reveal who was the supplier of his refoam kit. If he has had a truly bad experience then perhaps the forum members would benefit from knowing this and I would hope the kit supplier would be interested in the feedback as well.
