Having just received a new car in blue, I was previously using Turtle Wax car shampoo and found that it left lots of white marks and streaks on the car. This was advertised as streak free, so thought it would be worth a shot. It doesn't bubble up like traditional car shampoos, but is certainly a lot more streak free and washes just as good. If left to dry I still get a few water spots, but using a synthetic chamois and car looks great. Will buy again.
