How to fix these rusty areas? (photos)

These are behind the chrome hood trim, each mounting hole looks about the same. I assume it's just a matter of sanding + primer, but I wasn't sure the recommended grit. And will it hurt to just use some white primer and no finishing paint?

 

 

 

 

 

This one really pisses me off, was not like this a month ago (damn rain). I'm thinking about getting a can of POR15 and treating some of the undercarriage - do I need to do anything to this spot before applying it?

Wire brush it and paint it with por-15,As far as the hood I would replace it.

If that's all the rust you have on the hood I would clean it off with some 40-80 grit and/or a wire wheel - whatever it takes to get the paint/rust off and to get the metal clean as possible. Then check with Eastwood or a company that deals with a chemical rust treatment product and a good self etching primer/sealer. Are you planing on a paint job soon? Even with a primer/sealer I would get paint on it ASAP.

KBS coatings is better and cheaper then por-15.Check them out on the web.Just dont get it on your hands.Takes about seven days to come off.

The hood has overall really nice paint, hoping not to respray the thing just to treat this hidden spot behind the chrome trim. Picked up some sandpaper and self-etching primer today, will post progress photos.
