... have you ever had one tube of paint that drives you mad?
I have a tube of Mars Black acrylic paint that I've needed to use pliers to open from the very first time I used it. I don't have this problem with any other colour, and I treat all the tubes the same; try to avoid spills, let the paint settle back in the tube before I put the top on, loosen the top a quarter or a half turn after I've tightened it. It's a 60 ml Windsor & Newton Galleria tube, and it's still more than half-full, so I don't want to junk it but the tube is twisting so much that I have visions of it splitting and black acrylic paint going everywhere one of these times when I try to open it.
Anybody any ideas as to why this happens or what I can do to avoid it?
