    So, I found two abandoned scuba tanks today. They are both AL80s, both have 10 years since last hydro, and both had their valves OPEN when I found them. Externally they seem to be in okay shape.

    I figured I could get them hydroed and VIP'd and have myself some cheap tanks, but finding them with the valves open has me a bit worried.

    Does this make it likely they are rusted inside? If so, would a tumbling put it right? And what will all this cost me?

    Kewl.... wind chimes!

    Aluminum 80s don't rust inside but if they are 10 years since their last hydro they are probably the *bad* alloy.

    Still they might be worth a tumble.

    They may or may not be good, but they won't be rusted.

    Well... first ascertain the manufacturer and date. Then call around to the various dive shops and ask them if they will fill the tanks if they pass hydro, vis and eddy current test. The shop that says yes is the one to take them to.

    Some shops in FL, and other states refuse to fill any tank made with the 6351 alloy (susceptible to Sustained Load Cracking of the neck threads).

    What's the original hydro and manufacturer of these cylinders? If you let us know, we can tell you if they are good or not...
