I also use the Americana wax a couple times a year (before and after winter storage), The Buttery wax is an easy on - easy off application. I applied the wax to the whole car, then wiped off very easily. From watching Adam's video on Buttery wax, he said that it lasts about a month or so, and that it doesn't build up when reapplying. So I will apply the Buttery wax once a month during the summer to maintain the shine.
