Sorry, it's the nature of the beast. I just end up buying multiple bottles of CA in case one just clogs up. No matter the brand, technique I use the glue will gel eventually, causing me to throw away most portion of the glue. Therefore I just buy the cheapest brand out there rather than any premium brands. Helps to buy smaller bottles, however I found larger bottles tend to last longer than the smaller ones. I've basically taken to just opening the tip until you can practically fit a pencil through it and just use it until the glue gels or becomes useless. Helps to build a cradle for it so that you do not knock it over.
