Hi

To saaya
Please bee fair, do not talk about 'paranoia' when its af fact that corrosion always will ocour when you have two differnt metals and some moisture.
Please read this:
Corrosion Process...http://www.roymech.co.uk/Useful_Tabl.../Cor_basic.htm

Corrosion is a chemical process resulting the progressive destruction of a metal by the interaction of the local environment. The process results in the eventual failure of the metal with resultant high additional lifetime costs.

In the actual case the Foxconn alluminium NB-top will soner or later suffer corrosion and becomme a risk for leaks
