Letting it warm to room temperature brings it back to the same consistency it was before you put it in the freezer. No harm done. I have 2 liters of 100mg/ml nic juice in VG base in my freezer. It will be around 6 months before I need to use any of it.Taking a guess for long term storage how much difference would there be in storing the nic in the fridge compared to freezer ?
Have the current lot in the freezer but most the time freezer is foolish.
Also for the nic with vg how thick does it go in the freezer , nothing letting it sit at room temp for a while won't fix ?
Regarding coils: it's only logical that spaced coils are harder to space evenly than tightly wrapped coils that are touching each other.
