Oxidation/Rust on hood hinges
 

My '07 is showing signs of oxidation on the hood hinges. I have to assume rust is present on the hood under the hinges. I understand that the door hinges will eventually oxidize/rust also. From reading many posts it seems the only permanent solution are stainless steel hinges. Besides the hood and door hinges are there any other parts that this will be an issue with?

Thanks,
