I used to use epoxies for bonding but now I only use methacrylate adhesives. They are used for gluing the aluminium monocoque of the Lotus Elise together, as well as gluing aluminium sail tracks onto carbon fibre masts for the super maxi  yachts, with no rivets at all. Pretty awesome stuff. They stick to glass laminates much better than anything else I've ever used, as well as gluing aluminium and a lot of plastics. The only thing I wish they would glue properly is Nylon, but then I don't know of any glue which does actually give a chemical bond with nylon.

Here's the stuff I use, it made by ITW-Plexus, although in UK I believe it's the same or similar to Devweld 530:

I use the MA-310. It's thixotropic, sets pretty good in one hour and sticks like crazy. The really good thing about them is they can stick to oily surfaces, they are so aggressive they will eat through the oil - although I would always recommend cleaning the surface first. I use MA-310 in the construction of the SM110-52 EDF unit, for gluing the aluminium casting into the polycarbonate shroud, as well as gluing the carbon fibre spinner onto the carbon reinforced polycarbonate rotor. It also glues PETG, which is good if you mould canopies from it.
