simple answer, in my opinion, yes.
totally ruined
freeze a bottle of beer. then defrost it and drink it, "ruined"
someone said on an earlier thread that pre spray gold is ruined once frozen so i presume its the same for every chem.
brought all my chems in, end of september, mrs don't like it. back out end of march.
i could be wrong though. hope i am for your sake matey.
