The 40 Ford's hood is very original. Likely painted only once - and perhaps not completely - maybe just in the repaired spots such as where the latch plate was bolted to the hoods edge as shown below.
I attached the latch plate to be sure everything lined up before I formed the other two ends and welded them in. It's pretty close, which at least shows us that the hood is somewhat even, side to side - not pushed over or buckled anywhere.
Having not been re-painted, one can see there's a lot of deep surface rust that needs sandblasting.
The hinges will need to be straightened, plus new rivets installed to tighten them up:
