I would like to wax more often but unfortunately, don't have the time. Plus with all the rain here, it is discouraging as the car would be dirtied fairly soon after any detail. That is why durability is important up here for me as it is difficult to coordinate a day off with good weather. That is also one of the reasons why I currently use Zaino...for the durability, though I don't seem to get the durability quoted by others on Autopia. Get about 4.5 to 5 months max. Maybe due to the rain again? I try to put on a layer every 2-3 months or so.
