well i was informed that it would soften / remove quite a bit of the traffic film build up on the car.
I did as i was told with reccomended amounts, even putting more in than i should and it foamed loads and once left for 5 - 10 min, came back to wash off and see what it had done and to be honest it had not shifted anything...
so i went back to the good old 2 bucket and mitt method!
