Would it be possible to "re-glue" a delaminated outside wall section? I've been looking at some older 5'ers and some had previous water leakage (since repaired) that caused a "bubble" to form in the outer skin on the side. Would it be possible, using some type of "syringe" or small cut to "inject" a glue or epoxy between the sheet and wood or whatever is on the inside? Or, would the wood on the inside be too damaged to hold it in anyway? For clarification, I'm only talking about small (less than 4 or so sqaure inch) areas. I know we've done this before on kitchen floors and had it work fairly well. Any ideas would be appreciated.

These walls are made by pressing them together. How to duplicate pressure from both sides of a RV wall is yet to be performed on a completed RV.
This website details how to repair surface damage and repair through-holes in a laminated wall, but doesn't address repairing delamination where there is no hole through the wall. Good luck with your venture.

Thanks for the link. I'll look into that. Maybe something on there will help guide me.
