nice information. Iam hearing it first time. But the cylinders wont wear any ate now a days. They are all worn out and no paint is seen or no date is mentioned.
In this case, you can ask the concerned person about the expiry details. Once you ask all these details, next time they will bring the cylinder in good condition. Just try it.
You can also talk to company's consumer care department regarding this.
