Hello,
We use Paraloid B-72 to label our artifacts. With each bottle, we find that we are unable to use the last 1/4 because it has become too tacky and almost
solid. I believe that I heard you could add acetone to the B-72 to make it usable again. Has anyone done this and have it work as it always
did? How much acetone do you add? I really appreciate any information anyone has on this topic.
Thank you,
