I have several tubes of the inspection lacquer that are a year or so old but have never been opened. I tried to use some today, but the stuff inside has already partially solidified. I tried injecting MEK in one tube, and lacquer thinner in another tube and then massaging the fluid into the goo. Neither seemed to do much to get the stuff to squirt out of the squeeze tube.
Is there any way to rejuvenate an old tube to inspection lacquer?
