Someone has probably answered this question before? But I still need some help in deciding between a good 100% Carnuba Wax (liquid Simoniz 100% Carnuba Wax) or a Liquid Galss that I can purchase from an autobody shop? I live in Northern Ontario where are winters are harsh to say the least. Alot of road salt and sand. the summers are sometimes hot. OK not like the southern us but for us here it's hot. So what do you think? Wax or Liquid Glass? Thank's; Richard
