I've had the same problem at 4 museums where I've done work in the past few years.  (It almost drove me back to nail polish.)  I actually did use nail polish remover with acetone to open the jars of both clear and white B-72, putting drops of it around under the rim of the lid.

That's a real problem.  I was doing contract work for small museums with very small budgets.  A bottle, if it didn't dry out or become impossible to open, would have lasted over a year.  But it seems to last a few weeks before it's completely unusable.  Titanium white paint on the swatch of B-72 was recommended to me by a conservator, so that's what I'm recommending to the small museums staffs with whom I'm now consulting.

Hi, folks,



I’m wondering if anyone else has this problem – the only white labeling medium that seems to be available right now is the acryloid B-72 available from, I believe, University Products. My collections volunteers and I have a devil of a time getting the lid off. This sounds silly, but getting the jar open to label items involves a lot of hot water, use of a jar opener, and attempts by several individuals before we can break into the thing. We’ve tried leaving the lid on looser, but then the whole jar just dries up. We’ve also tried painstakingly cleaning the rim of the jar before closing it again, but that doesn’t seem to do the trick either. We don’t have the same problem with the clear, strangely.



Any ideas? Is it us? Should we be doing more bicep curls? Is there another product that is easier to get to that we should know about?



Thanks in advance!

Erica
