RE: Here's a simple tip!
After a 3 month plane building hiatus, I went back to a 4oz bottle of thin CA to which I had put on a capilary tip....
The CA flowed out nicely, w/o my having to do anything.
I think that it is important not to retract CA that has been exposed to air, back into the tip accidentally.
That may have been why I saw no clogs over time.
