Used them on my 1/96 Constitution and 1/350 Titanic. Used Gorilla glue to attach them.
You may have to trim the edges if there is any excess along the edges, even minute.
They do raise the planking so watch for fit on upper decks as that could be affected a little.
They come rolled in the tube as it is sturdier packing and offers better protection. Before you begin to mess with them, untube them and lay them flat with books or something to flatten them out, and leave them overnight. They really dress a build up.
