what I meant was use epoxy primer on both hidden sides. this seals the metal. regular autobody primer all by itself is actually porous so it will eventually start to rust behind the panel you apply. soon the adhesive will let go.
I guess you could use epoxy of some sort to bond the new panel to the old panel.
I assumed you were installing a one piece panel over the engine side of the firewall to make that area look smooth and cover existing holes. are you installing on the inside of the cab instead?
