Gorilla Glue to repair Delamination

I have some delam starting under a window due to my failure to keep it sealed at the top. I inquired about repair at the local RV place and was told that they use "hi-temp" contact cement. Once the area is opened and allowed to thoroughly dry, the delaminated sections are pulled as far apart as possible and each side coated with contact cement, when the adhesive is dry the 2 parts are clamped together and allowed to set. The dealer said the reason you need the hi-temp stuff is that the walls get hot from sun exposure, and any other adhesive will fail.

I haven't actually done this repair so I can't speak first hand but thought IO would pass this along from a pro in the field. You may want to PM Chris Bryant here on the forum, he is an RV tech.
