I used Nexgen Waterless Wash on my wife's Genesis and it was easy to use and really worked well. We live in the California Central Coast and with the recent rains, her car was pretty dirty. I used the washerless wash and about 5 days latter we got hit with more rain and I couldn't believe how clean the car looked after the rains. I included a picture of her car and I have not touched it up, this is three days after our last rain, and yes, we did drive it.
