- No, I wasn't joking. I was simply pointing out a few observations that anyone

- 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).
