Ken's right, the simple mirror mod will slow down the corrosion factor, but if you have a bad set of hinges, they'll corrode anyway. My hood hinges were just as bad as the doors. It's the low quality metal that's used in the hinges. If there's a minor flaw in the paint process, the metal will start to corrode and bubble the paint. That's what the body shop guy told me.
