You see, when there are 2 metals that are not the same that come into contact with each other, a chemical reaction usually takes place with the introduction of moisture. This reaction is bad. That anti-corrosion treatment is to protect the areas from moisture.

Good info. Suspect that galvanic corrosion is accelerated with the salty air during shipping and that is why they spray those areas. It does not last however, and is slowly evaporating with the engine heat. Good to pay attention to these areas over time and note any issues. I know Volkswagon used to saturate their engine compartments with a similar stuff. Do most people just let the "stuff" evaporate over time or do you recommend something different?
