No, I wasn't joking. I was simply pointing out a few observations that anyone
who pays attention to aluminum in a household environment might make.

I was most definitely *NOT* talking about anodizing aluminum (though I've got a
baseball bet that went through that process).

For those who dont understand:  See if you can find a friend on the east coast
of the United States.  This friend will almost certainly have a storm door or
storm windows that are made of aluminum and are exposed to the weather.  Such
windows or doors will almost certainly be coated with Al2O3 (aka aluminum
oxide).
