Velcro hook detaching from bed extention

Hi all. I have a 2010 173t that I bought recently and I just took it out this past weekend and noticed that the hook velcro strip that runs around the fold out bed in the rear has become detached. I saw this beginning to happen about a month ago, but the glue was still very sticky and I got it to re-attach. It has not come all of the way off, due to the screws that hold it in place periodically. However, it still leaves foot long+ sections open to the weather around the bed that you can see out of. My question is this, for all of you more experienced folks: What can I use to re-attache the hook strip to the aluminum? Would gorilla glue do the trick? Any ideas or suggestions would be most helpful! Thanks!
