I use the original staples and  a small pair of pliers to get the bend started and then use another pair to get it tight.  It’s a bit of work but can be done without using any messy adhesives. The seal might have a wavy look to it when done but this can be fixed by using some super glue and small clamps to hold the seal tight to the hood while the glue cures. It might take a day or two but doing a little bit at a time will give you a professional looking result.
