Extremely easy to apply and wipe off so that you could do a clean car in less than 30 minutes. If durability is really bad you can still do it every couple of weeks and it goes on super thin so a tub will last a very long time. It apparently can be layered (24 hours apart) so I would expect a couple of coats would provide 6-8 weeks durability anyway.
Seems to reward you with excellent appearance with very little effort or material. I agree though it would not be a winter wax.
