I tried jb weld once, didn't work for crap, but what the guy said above the gorilla glue will also dry hard (not nearly as quickly as hot glue will) so be sure to use something to make the edges smooth, I am assuming this is just to prevent the edges from lifting up anyway so it really shouldn't matter, I am thinking maybe use something to cover the edges that gorilla glue wont stick too so you can just peel it off afterwards but I don't know of anything it wont bond to so you might do some research online for that first
