I have been using it for a while on my PT and will continue on the Xfire. I did not like spraying the soap on the car and sponge however. Now I take 2 ounces of the soap and put it in a bucket of water (a couple of gallons) and wash from the bucket rather than dispensing it from the unit. I just use the unit for initial and final rinse. The results are fantastic. No drying and no water spots on the finish or the windows! Don't be alarmed when the soap or rinse do not bead on the finish. They are not removing your wax. When the car is dry it will still bead water.
