Hood scoop adhesive

There are adhesives that will work for gluing a scoop to a hood but the problem is getting a what I assume is a fiberglass scoop to stick to a metal hood it will work for a time but it will also crack and delaminate over time, so to be safe I would drill the holes in the hood, or what about getting a second hood that's in good shape and install the scoop on that hood and save your original hood if you ever want to go back to stock
