I am curious when polish is exposed to freezing temperatures does that cause it to become extremely liquidy? During the winter months I once ordered a large bottle of polish and it was shipped. Once arrived it was way to runny. This makes it very hard when polishing and you put it on your pad, it can run off very easily and then your wasting product.
If it is from the cold I guess it would have to be shipped in a heated truck which no doubt would cost a fair amount.
