Try contact east. They have Kester no clean and others at good
prices..
As far as longevitiy, I have had my tube for over a year and it works
just fine. I do keep it in my refrigerator, capped on both ends and
with the tube opening facing down. May not be suitable for production
quality work, but it is fine for hobbysist.
A few months back I ran into some problems with the applicator
clogging a little too often. I just squeezed a litte extra out of the
tube to get to paste that was probably not quite as dried out. Have
not had any more problems since.
