Forget about the Z****_and the N** for now, I think both of them got enough attention/hype already. There are a lot of under-rated waxes floating around, just have to look for them. Maybe it’s time to get a better/clearer picture of durability. I am in California, Orange County specifically, so durability is not a major issue. It seems to me that you are one of DA MEN (a compliment, not an offense), been there done a lot of waxes and in the best condition (oh yeah,winter in Canada is pretty brutal) of giving a better picture of durability. If you don’t mind, could you tell us how your car is used in those 6 months - a garage queen, outside 24/7 days/week, a daily driver, etc…. and how you maintain it (I guess your car would be fully detailed prior to the winter season). This will help greatly.:xyxthumbs
