I bought this 2 months ago and have used it multiple times to wash my car with a foam gun. Does the job wonderfully and leaves the car shiny. It's not too strong so the paint still looks fresh on the car. Since it's a little mind detergent to protect paint, it has trouble removing some stubborn marks or dirt from the surfaces. You would have to use a cleaning cloth to clean that off. For me that is better than buying a stronger detergent and destroying my car's paint.
Good product cleans car. Not as sudsie as I thought
