I suppose I should elaborate on my experience, because I've put a bit of time and thought into the storage of CA to extend life. Some of the old-timers around here may remember an old thread about this. Might be in the Library, but whatever...
Keep in mind, as Randy said, keeping the glue away from water is what will extend it's life. That's why it's sold in HDPE bottles (high density polyethylene), which is essentially super-wax, and is great at blocking water vapor. Also, the glue does not stick to HDPE very well. Even the spouts of the foil tubes is HDPE.
We are not talking about liquid water - it is water
vapor that is the culprit. So, for practical purposes: humid air.
So ... how do you keep it fresh? Simple, cap the bottle and create a hermetic seal against the air.
You say: "Yea, right! I capped the damn bottle and it still turned into a frosty nugget of plastic."
This is where a little OCD could really help. Not confessing, just sayin'
The bottle caps are designed to seal very well, and they do! However, they rely on very narrow rings of plastic interference to create a seal when fully engaged. Those sealing surfaces need to be kept clean and free of hardened glue to work.
So - here comes the OCD part - on those regular bottles of CA with a needle like spout and tall cap that snaps on, if you wipe the tip off with a paper towel and cap the bottle EVERY TIME you use it, the glue lasts till it is used up. I know, I did it. Crazy, I know.
What normally happens is you either forget and leave the cap off, or you just jamb the cap on there with a little glue that has dripped down the spout. Once that glue hardens on the spout and in the lid you are done, its just a matter of time till you have a frosty nugget of plastic.
The thing is, if you keep the bottle totally clean, even if you leave it open for some hours, and you have to pick off some dried glue off the spout, the glue lasts a LOT longer.
For the little tubes, I put a small brad in the tip to seal it, and even the tubes last a long time. I just used the last bit of one that has been open for months - yep
months and I'm not BS'ing you.
I don't know. Guitar building is kind of a fastidious process, so this just fits right in for me. I'm not OCD - I just asked my wife who has a degree in Psychology and masters in social work, and she said "no". I don't check doors 3x if they are locked, none of that.
