To put it short, do most bottles have a protection thing on them to stop them going Boom! if you overfill it a tiny bit?
Over Filling Your Bottle

Yes, its called a burst disc, every air system will have one. If you over fill it will blow and release the pressure.
All bottles have a burst or rupture disk built into them (if you look at your bottle, there should be one or two raised hex nuts with 2 holes on either side of each). These act as intentional weak points in the structure of the bottle, ensuring that these blow out and release the internal pressure before your valve does. Most of them don't go if its just a little over, the disks on a 3000 psi system for example need 4000psi to burst, because the manufacturers work a little fudge factor in their bottle design (but while a 3000 bottle may be capable of holding more than 3000psi, don't ever overfill it!!! there may be a weakness in the structure of the bottle that could fail if it is overfilled, then you'll have to explain why you had 3500psi in a 3000 bottle). The disks cost about 10-15 dollars US apeice, and should be installed by a licensed airsmith. While they would blow if they are overfilled too much, they are really in place to guard against a change in internal pressure, like moving your tank from the shade into the sun for an hour or so. An increase in pressure like this is really more of a concern on C02 tanks, which is much more susceptible to temperature fluctuations, but it can be a concern on air tanks which are filled to the bottles limit anyway.
Crap, I spent 10 min typing out a lengthy and detailed reply, then I get beat out, and now I look like a jackass trying to look smarter than the guy before me.
I know that 3k bottles are tested to 4.5k and 4.5k to like 5.5k.
Hence the disk being @ 4k instead of 3,200 or so.
Incase anyone was wondering

I may be wrong, but I think youd have to over-fill by quite a bit before the burst disc went...
Or does the expansion of the gas (if its CO2) mean only an ounce or two over and it will blow?

Did you ever think to stop when it got to 20oz????
Or did u think you would just carry on to see how much CO2 spray you could make come out of your bottle due to over filling
