For many automotive applications, Sikaflex tend to have the adhesive of
choice.

A good choice, Sikaflex is a polyurethane adhesive/sealant and will
stand up well to the conditions encountered by a vehicle. Silicon
sealant should also work well and has the advantage that it can be
cleaned from bodywork with white spirit (or tar remover) without
damaging paintwork.

A polyurethane adhesive such as Gorilla glue should work but it foams
and is IMO unsuitable for vehicle applications. Sikaflex doesn't foam
and stays where it is put.

Water-based domestic acrylic sealant is the choice of fools.
