Personally, I would use nothing but Polyurethane glue on the fuse. I have been using it to sheet foam wings and I am absolutely astounded with the bond. It beats anything I have ever used, including epoxy. As already stated, use wide masking tape to secure the sheets to the fuse contour. The glue will expand, but not nearly enough to break masking tape. Masking tape is one of my most used tools.
