Yes, I read that also and have always done that since. Another thing that seems to help a bunch that I forgot to mention... since humidity is even worse than heat for CA glues, I store my CA in sealed mason jars with desiccant packs inside.As far as glue going bad someone on here a while back said to always squirt out the first drop or two that comes out of the spout and don't use it.
That makes sense because we all know the glue starts to cure in the spout. I have use two and three month old Loctite Professional with no problems.
I get the ones that color change and are microwave rechargable. But still won't go over three months after opening. I live in a low humidity area but it still seems to help. If one lives in a high humidity area I can see it going bad in a month. These glues are only 5-6 bux but I just hate to waste stuff unnecessarily.
