Mixed at the correct dilution it should be fine. The durability of any wax is very dependent on conditions. Car parked outside 24/7 or in a garage day and night, etc.
It's parked outside 24/7 and 90%+ highway commute miles, so bugs are a big issue and road tar. Also tree pollen over the driveway. Our house has a garage, but it's more like a storage shed than a garage.
