Query: Doesn't keep

The problem with this and the Gorilla Wood Glue is that although they perform very well, they do not keep.The container and cap are poorly designed. Once opened, within a month or two, the entire bottle has solidifiedso for an occasional user like myself, it becomes a very expensive product because I get one use out of the bottlebefore it hardens up on me.Can't fault the product... I glued a block of wood on a wooden gate 3 years ago and still holding strong but I wish they would fix the cap.I bought a small bottle after the first one hardened up on me. The second bottle hardened up inside the bottle before I even had a chance to use it. The product itself works well but it does not keep. They need to market it in smaller bottles or do something to improve shelf life.
