HYDRO STOP is a unique spray protection, it is not necessary to wipe. It is designed based on quartz which repels water. It can be applied on all surfaces of the car: Bodywork, glass, plastic, hood, rim, wheel arch. Provides better hydrophobic protection, durability and shine.
Used this product right after a wash on a decontaminated vehicle with no protection. I sprayed and rinsed and saw no difference in hydrophobic qualities. I also tried this on a coated vehicle and the hydrophobic qualities remain the same. No worse or better.
I like being able to spray and rinse. Less work.
