Terry,
You are right in that they were assembled with a spray adhesive. At least mine were.
When they delaminated, I put them back together with moistened Gorilla Glue (a single part moisture activated polyurethane). I was ready for it to
swell on cure, so I had it supported on some 2*6 as strongbacks and used about forty clamps (when my father and I built boats and spares we needed
lots) to hold it from swelling and puckering during curing. I could not use an epoxy as it needed to fill a number of gaps that were probably OE.
Both that and the hanging locker (closet) door are good now.
