Of course there's no such thing as self dry... wala naman magic yan eh, but it's a decent shampoo, I like it as well... but for its price, i'd rather go back to my usual Mother's Trigger Wash and Eagle One WET...
if your car is well waxed and clayed (eg: smooth surface) kahit anong car shampoo na ok naman can be "self drying"... Just use the sheeting technique when rinsing...
