Scrim Shield tape. It's made for use unser RVs. It's 4" wide and comes in 180' and I think 25' too. An RV dealer or parts vendor will sell it by the foot. Coroplast is made from polypropylene and just about all glues & adhesives will not work well in the long run (look up manufacturer's info.). Mechanical fastening is the best approach. A piece of sheet aluminum maybe 3" wide would work along with self-tapping screws. Our dealer used some Scrim Shield tape on our underbelly and it is starting to peel off a bit after 2 years.
