I neither would place any "premium" on unopened cans of anti-freeze. The stuff will discolor lithography if it gets on it, and over time if it starts to leak, will take the litho off. I see lots of antifreeze cans with 1/4 of the lower graphics gone when they sat with the contents for years. I've emptied all of my Mobil ones that were full, for fear of future irreversible damage.
