As a retired plastic technologist, I can say that there is only about 2 or 3 manufacturing companies who actually make Superglue because it is quite a specialised  manufacture process, Locktite was one and Permabond, perhaps one other who bought the license from Eastman Kodak when it was around. 

Most of the others are really distributors who repackage the same product under their name. I get my Superglue  from B&Q under their own Holden brand and it works just as well as other branded Superglues.

The question is more related to when you get Superglue mixtures made, where Rubber toughening agents are added in specifically to adhere to rubber, usually the black liquid versions. But do these types adhere to aluminium hubs as well as pure Superglue ?

And what of the other (non superglue) adhesive types you get with Gorilla Clear, or Flexible shoe glues ? I don't have any experience with these, so it will be an interesting experiment to compare them all using the same tyre compound and wheel rims.
