Do not put a damn sticker on it. Doesn't that sound like a freakin bandaid to you, literally? This is what you do need to do. Get that sealed up quick! If water penetrated the lay up it may delaminate the hood and you'll get a bubble instead of a scrape you have 1 option as far as I'm concerned in order to seal that up
Go to a surf shop or someplace like it. They probably sell board repair resin which cures by UV light. In this stuff is fiberglass as well so it will be strong. It usually comes in a black bottle and looks like glue. Pour some on and rub it over it and let it cure. To save time sanding it down put some plastic over the resin so you can shape it with your fingers whilst letting the UV in to cure it
