If you are going to do this water spray on the IC thing, there are coatings
available from the HVAC industry which can be applied to the cooling air
side of the aluminium to keep it from going away. Said coatings are not too
bad for the heat transfer, either. Don't remember names or sources right
now. These coatings are used on HVAC coils in salty air environments, and
they work very well.
