I've been working on a couple of older aircraft kits, two Airfix and one Monogram, where the the plastic formed spider cracks, splintered and literally had chunks come out when using Testors liquid cement to join the fuselage halves. It was an old bottle with very little left in it, which I susequently pitched in the trash.
I've been using this stuff for 30 some years and never had anything like this happen.
Any thoughts or suggestions?
