Thank you for all for your help.
I have started to do repairs to the bathroom exterior wall in preparation for a liftable grab bar next to the toilet.
Indeed, I did remove as much of the luan as possible. It just was not worth saving. Unfortunately, the glue used to sandwich the foam insulation between the luan layers is very strong. There is still a thin layer of wood fibers attached to the foam.
My plan was to remove a chunk of foam between the horizontal square tubing then fill the cavity with two layers of 1/2 inch plywood. I used PL Premium to adhere the plywood to the exterior luan and the two layers together. I then used Simpson ties to attach the plywood to the tubing.
I then purchased 5 mm luan at Home Depot and attached it much the same way the manufacturer did. I used extra hold PL Premium this time.
The one problem is that 5mm luan is thicker than what the manufacturer used. This created a rise in the back wall. I took some left over melamine that I plan to use on the wall and cut that in strips and placed that on the good portion of the wall on the left. The two surfaces are almost level. I also cut out the areas where the Simpson ties are connected. Placing the luan over the ties was not possible with the screw heads sticking up. I filled the notch areas with PL Premium and melamine or foam insulation, whichever was closer in thickness.
