67 hood repair

[kgmunro]

So on my 67 c10 some one has mounted one of those ugly bug deflectors years ago, drilling four holes in the hood. they are right where there are no supports , kind of where the hood would be tin can like when you push on it. How can these be repaired? I want to weld the holes but am sure it would warp bad with little heat. My friend mentioned using the glue they install body panels with and glue a small repair patch from the underside and skim coat it with fill...any ideas??
