Didn't work.
This product did not work.  I followed the directions.  I washed my new car for the first time, less than a month old so not too much road grime.  My daughter had drawn a smiley face in the dust.  After using the whole bottle in my power washer for one car wash, I could still see all of the dust and the smiley face.  I had to go back and bucket wash the whole car.  I wish it worked.  I drive a minivan and have 3 kids.  A bucket wash isn't high on my priority list, but I want to take care of my car....  I will say the wheels look better than they did before, but the car did not.
