That's a tough call?
I think something like Carpro Cquartz has some form of a volatile carrier solvent. Might it freeze? Possibly in sub-zero temps, but think it's more impervious than say water is.
Possibly the carrier solvent is something like Isopropanol? (An Alcohol)
The surrounding of a Cardboard Box, and Packing Materials should also help some from vicious cold exposure.
Right now, and how the weather has been, I think you'll be OK.
