Tools & Fabrication - firewall repair

I am in need of repairing the firewall on my camaro so I am sandwiching 2 peices of metal together and using some structural adhesive to bond everything together...but I don't know which adhesive to get.....any ideas????

try some epoxy .

PLEXUS Methacrylate. cant remember the exact part# but they have a bunch of different kinds for bonding metal to metal or metal to fiberglass or you get the idea. just check out their site
