I have been researching this and found an interesting article from one of my suppliers, camcarb. They recertified and filled my 10 lb luxfer aluminum co2 tank. Basically, plain old co2 just wont cut it anymore and a mix of some nitrogen with co2, called beer gas is best.
apparently industrial co2 is inferior to food grade beer gas. Might explain foam issues when getting refills from the paint shop store.
A saw a similar article on a site called perfect pint; don't have the link - google it. The gas you use is for storage and dispensing is becoming important to the finished brew quality and characteristics. A bad pour can ruin a great beer.
