Hanno,
Apparantly the well known two part epoxy adhesive, Araldite, was developed for the aircraft industry and used in construction of the DH Mosquito. As this was mostly wood, I am uncertain as to wherther it was also used to bond metal surfaces. My experience of Araldite with metals is that its adhesion is not great, even with the best prepared surfaces. Where as Loctite Multibond, sticks like sh** to a blanket
