Hey Cy or anyone else who might know,
I've got 2 bottles of MAG-10 I was planning to save for a number of years. In order to store them I opened the bottles and switched them to a less "suspicious looking" bottle. Damn stupid looking back given the fact that they'll probably expire more quickly.
I'd like to save these for a number of years until a rainy day. I know that the regular life expectancy without freezing is 3 years, any idea of how it might have been reduced without the airtight seal?
