[Nhcoll-l] Paraloid B-72 applicators?

[Shoobs, Nate]

Hi all,
I use Paraloid B-72 to repair shells that have been broken, and to prepare shell surfaces for labeling in cases where the material doesn’t hold ink well.

While the repairs it makes are beautiful (often I can’t even tell that the shell was broken in the first place), a great frustration of using B-72 is how messy it can get, and how quickly the solvent evaporates (which changes the concentration).
I have the resin pellets and mix up new B-72 in acetone, and currently we apply the B-72 with little brush-bottle applicators supplied by University Products with their pre-mixed paraloid.

However, it only takes a few uses before the threads on the brush-bottles get gunked up, requiring acetone and a lot of grip strength to reopen.

Is there any clever solution for this?

Also -- has anyone tried “fineline applicators” with b-72 before?
Best,
Nate
