SIKAFLEX....it's an isocyanate-curing polyurethane, iirc.
use to stick alloy car panels together and alloy to steel also to fit bonded -in glass.
Yhe stuff is rubbery when set and you can get high and low -modulus types. As with Epoxy (or soldering/brazing ) a relatively thin film is stronger. metal sheet will tear before the bond breaks.
Prep and priming are the key to a successful long-term bond.
