What glue for delaminated fiberglass sides?

Question

Just about to get all of the delaminated luan wood off of the fiberglass exterior walls. I'am going back with a new sheet of luan when I get this all cleaned off. Just checking with you all to make sure what I'am doing is a good idea. Basically I'am cleaning this down to the fiberglass ( using 100grit sandpaper). Then thinking of using contact cement to glue the luan back to the fiberglass. Figured this would be easy to do considering where it's at. Should be similar to installing formica on a countertop. After that's dry then just liquid nail it to the studs. Any comments appreciated.
Fyi. The wall is about 4'x8'

Adding another pic to show that I can fold the fiberglass way back to give me room to work. Now I kinda wonder if I should glue and staple the luan on the studs FIRST then use the contact cement to install the fiberglass last. This seems easier.

I know that some use Finishing Resin, as in the resin used originally to create the fiberglass it's self. This is when they need it to flow into the voids of the delamination. In your case I'd try something like a tile floor adhesive. No matter what you use how will you apply pressure on the parts glues together in order for them to bond properly?

Ya that's a problem. No easy way to apply a lot of pressure. Might can put something thick like a 2x block behind the wall temporary and beat wall with rubber mallet. The instructions on the contact cement said so, as last resort.
Not sure about the finishing resin. Don't know what that is. I'll look it up.
The floor glue is a good idea. I've used different kinds. Some of it does not require lots of pressure and sticks to everything.

The problem with using contact cement is that if anything isn't positioned correctly, it can be a bear to remove and reposition. If the fiberglass exterior panel is rigid, this will be less of a problem. I would lay the panel down in increments and roll the fiberglass into the luan. I'd probably also fashion some type of brace or clamp to keep pressure on the exterior panel.

Fastening the luan to the framing would be an excellent idea.

I think Dicor makes a glue for this, check camping world or other RV outlets.
