How well does PG based Nic last in something like the freezer? Is it advisable? Doesn't look like I can get my larger bottles in VG so I am curious about picking up a larger order of PG and put in the freezer like my VG.
PG will hold up better than VG in the freezer. I have some in PG base that has been in the freezer for 2.5 years and still like the day I bought it. It is thought that it may hold up as long as 10 years kept in freezer, maybe even longer.
