Applied it to our SUV prior to leaving for the midwest. Granted we had a couple snow storms (one in Montana, and another 3 inches in Cheyenne) and I took it off road up to our property (I had mud on it reaching the top of the roof in the rear, wife made me wash it all off after a couple days as she got tired of my "off-road badge") the P21S carnauba was completely gone once I returned home. It lasted 4500 miles, 1 off road trip, and 2 car washes...a total of 2 weeks.
