I fish all winter in freezing weather, often in sub-zero temps. I find it's more trouble trying to put stuff on the guides to prevent freezing than it is to periodically just break the ice out with one hand while holding my rod with the other hand. If it's cold enough to be wearing gloves, I don't have to remove them to do this, but just have to be reasonably careful not to put so much pressure on the guides that it might break one of them or the rod tip. Overall, this takes less time than putting stuff on the guides to prevent icing, although I do have Stanley's Ice-Off but rarely use it.
