A coating composition that can be applied to a vehicle as a rinsing and drying aid after the vehicle has been washed is disclosed. The coating composition may be prepared and sold without water as a dilutable concentrate, or may be sold in a pre-mixed diluted aqueous solution to which additional water may or may not be added at the vehicle washing installation before the diluted coating composition is applied to a vehicle. In one embodiment, the composition includes water, a non-chlorinated cationic emulsifier, and a petroleum-based hydrocarbon distillate oil, wherein the weight ratio of the petroleum-based hydrocarbon distillate oil to the non-chlorinated cationic emulsifier is in the range of 0.5:1 to 10:1.
