Need epoxy to bond aluminum to steel

I cut out the tubs in my trunk and want to seal it off with flat aluminum sheet. What can I use to bond the aluminum sheet to the steel body?

TIG... I'm not sure about the metal compatability.

I'd use thin sheet of steel, weld it together, and paint it.

Aint gonna weld aluminum to steel.

I would rivit and use JB Weld or RTV. If you want something permanent get 3M Marine 5200 sealant, Ive seen that stuff delaminate fiberglass before pealing off.
