Correct me if im wrong

Correct me if I'm wrong, but if a tank is rusty over its entire surface -
especially round the neck, isn't that time to throw it away?

Well, possibly. It depends on how bad the rust is, and whether it's just
surface rust or the structural integrity of the bottle has actually been
compromised. If it's just surface rust you might be able to get it cleaned
up and back into service.

Thanks. Let me be more specific. The rust (no attempt to cover it with paint
and it is all over) is at a level where the surface of the bottle has pitted
and looks more like a teenager with very bad acne.

I was once left with no option but to throw away a cylinder which was in
that condition. - It came back from a test, sawn in two :)

There are still two options:

1. Have it tested to determine whether it's serviceable or not. The odds
are, it's not, but the only way to know for sure is to test it. There's a
cost associated with testing, probably even if it fails. If the tank
passes, you're still going to have problems getting it filled. No shop
wants a tank that looks like it will fail hooked up to one of its fill
whips.

2. Chose to scrap the tank now and buy a new or previously owned one.
Personally, this would be my choice. I would rather avoid problems at the
fill station than save the cost of a replacement for the relatively shorter
remaining life of that tank. If I were to scrap the tank, I would drill at
least one conspicuous hole in it. The larger the better.

All this sounds very sensible to me. Now, what if I were to tell you that I
know of a dive shop (admittedly not in this country) that has their entire
stock of tanks in this condition - used both for training and for dive
packages. Oh and they all have dual 'o' rings on them.

I'd say it's pretty common, I know at least one operation in this country
I could say the same thing about and I know at least one that regularly
pumps fills contamined with oil. I avoid them... *shrug*

It's obvious that you want to bad-mouth some dive operation you've been
to. I don't particularly like the way you're going about it, posting lead
in questions to try and back the "group consensus" into a corner, and
then sucker punch us with, a "Oh, so this is a bad dive operation then"
type thing.

Either name and shame, and see if there is dissenting opinion, or be
quiet.

Would they also happen to give free fills (I've only heard one person say it
before and wasn't sure if they were just unlucky, but sounds like it might
be a more common problem...)?

I have had a couple of bad fills a few years back from these guys.
