Strange.

With the thin tube applicators ( the ones with almost a hair like thickness ) I NEVER take them off the bottle, and the applicator never ( or almost never ) clogs!

They are designed so that there is so little CA exposed to the air, that it never gets an opportunity to evaporate and harden.

I leave these on the bottle with no cap. Whenever I reach for the CA, it is ready to go and flows freely.

And I use these on BIG 8oz CA bottles w/o problem.

Bigger applicators will clog, but the capillary type ones are fantastic.

I've had the problem with the bottom cracking, but thanks to the mentioned suggestion of applying tubing ( GREAT IDEA! ), that should be a thing of the past.
