Fair enough.saf_25:It's steel, not AL.
Xanthro:I'm confused as to why you would ever need to tumble an AL tank. Even if the tank gets scratched, you wouldn't tumble it. Unless it is in contact with Mercury, AL doesn't really corrode, it creates al oxide, which is as hard as a sapphire.

JDog:Since we are on the subject of short fills. I have a question. Why don't they slide your tank in some sort of water tank, in order to keep the tank cool? I thought I saw this done in Hawaii 8 years ago, wouldn't this help keep everyone from getting a short airfill? Last week I waited for my tank to be filled (@ Sport Chalet), and when he handed it to me it felt very hot, I don't know how hot but when I picked it up it did startle me. It wasn't warm it was hot. I ended up with just under 2800 after it cooled off (will temp. make THAT much of a difference?), it wasn't a big deal this past weekend, because I ended my dive with 1500 but what if we were doing a deeper longer dive somewhere, I would have felt a little bad about getting a short fill.
