any way to fix this hood with sunken sheet metal? its perfect otherwise.

[sircrunch]

before i obtained this truck my nephew and uncle went a little haywire sanding and grinding the underside of the hood. when i picked up the truck and its pieces when i bought it, i was shocked at the shiny metal underside of the hood. it was so clean you could eat breakfast off of it. sadly though, i think that they went a little too far and got the metal a bit too hot and the metal may have also got a bit thin.

Now i'm left with a perfect, dent free, rust free, fully prepped SUNKEN IN hood. The hood still has the factory padding above the hood braces. In fact, the hood is nice and straight above the braces. The sheet metal is sunk down everywhere else. You can put the palm of your hand in the middle of the warped place and lift with very little pressure and it goes back into place. Let go, and gravity brings it back down.

I'm hoping to fix this myself. Perhaps with some sort of extra bracing. I'd love to keep this hood. Anyone got any advice or experience with this problem?

The hood is sunk down inside the red circles shown here;
