1967 Cuda FB project

I will probably drill holes for #40 cleco pins through both pieces before i disassemble the hood. This way i can pin it back together in the exact same spot. Glad i saw this, whats dropping out of my hood looks like rusty coffee grounds. I know its surface scale, but needs to be gone. After which i will epoxy prime the framework and hood underside where it cant be reached before reassembling it.

What do you recommend for the adhesive that holds both halves together in the middle. I work in aerospace and we have a 2 part rubberized sealant we use on aircraft. I was thinking

It can only go together the way it was welded because all 4 sides make a box for the inner piece.
Any glue that will withstand some heat will work. :)
