A few NOS parts

[67z28]

I picked up a couple , what used to be, NOS hoods and some emblems this weekend. The hoods were in their original GM boxes, but the Florida humidity and being stored in the rafters of a building did not do the hoods any good. For the most part the rust is minor surface rust, but one of the hood has 2 spots that are a little worse than surface rust. I don't want to sand and prime the hoods, so what would be the best way to neutralize the rust for now. Should I use a store bought rust inhibitor?

I also picked up some emblems that the boxes are not in very good shape with the hoods.

Thanks for any help.
