If you have a decent tank that dosn't leak it should hold pressure for a long time.

My tank came fron a neghibor, someone told him that after 5 years or so he should get a new one cause they could rust inside and explode. I think the guy that sold him a new one told him that... Iv'e used it ever since and if I run the presure down in it I promptly re-fill it when I get home. Never sees a day without air pressure in it (usually 120 lbs) and it hasn't exploded yet... lol.
Just remember, all that air in there can be heavy, so make sure you have it where you want it before you put 120 pounds in it! :alien:
