    Old can of tung oil

    I have a can of Lee Valley Polymerized Tung Oil that I sealed using a can of air to displace oxygen and using a pair of channelocks to tighten the cap, 1 year ago this month. It is still mostly liquid, but I have not opened it up. Could this still be good to use?
    I had used about half of the can back then.

    I read the oil has an indefinite shelf life. If it has skinned over, adding mineral spirits will refresh. It was suggested that you transfer remaining oil into smaller container to reduce air contents......rather I squeeze(bend) the can till the fluid reaches the top.

    Test it on scrap when you are nearly ready to use it. If it dries it's good
