Experimenting (on my nippers car) with the spotless water.
Quick wash and then sprayed the whole car twice and left to air dry in the sun.
Result !
So Im not going to be able to cheat and not dry the car, it works but I will still be towel drying because if you miss one spot you get left with water marks !
I was not able to get enough flow from the sprayer to get the water to sheet off especially as my drive is flat.
Wheels have air dryed well no water marks
Will I be using it on my golf, yes but I want to find a small pump to increase the water flow
