A few years ago I opened a long-time stored plastic can of anti-freeze, only to find that it had polymerised the container and was useless! That particular A/F also contained MEK (so I was later told). I'm a bit more cautious of what A/F I buy these days, and try only to buy enough so that it is all used upon installation.
