Engineering design is a complicated process that includes design for purpose, manufacturability, inspection, and maintenance.  One of the considerations often overlooked in designing manufactured products is drainage.  The corrosion of the automobile side panel above could have been minimized by providing drainage to allow any water and debris to fall off of the car instead of collecting and causing corrosion from the far side of the panel. 

All of the other methods of corrosion control should be considered in the design process.
