Just a matter of patching the hole, smoothing the work, priming and block sanding the entire hood and then Epoxy priming and painting. You could leave it in Epoxy primer if you want the flat black look.
It won't need to be re-gelcoated.
If you know how to worjk with fiberglass it is a piece of cake, your hood can be saved. Bodyshop or even a Marina(boats are fiberglass) could help you.
