Thanks for the replies. I'm on my way to the big store to get a roll of
Gorilla tape.

Second Gorilla tape. Have used it twice in emergency situations. That stuff holds!

Gorilla tape will work. I keep a roll in the camper for repair and patching.

I use Gorilla tape, available at Home Depot, Lowes and hardware stores.

I recently removed a 2' x 2' square section to access tank valves. I got a piece of material from a local sign shop to create an access panel. I secured it to the existing coroplast with short self tapping screws and then sealed the entire edges of panel with Gorilla rape. It holds well.
