CarPro Hydro2 Foam 500mL CarPro HydroFoam combines the coating properties of hydrophilic glass fibers and fluoropolymers that CarPro Hydro2 is known for with a pH neutral foaming wash. CarPro HydroFoam is extremely versatile and can be used on many different surfaces; wheels and wheel wells, calipers, glass, and even plastic can benefit from a wash with CarPro HydroFoam. With no cure time necessary, your vehicle is immediately cleared for use as soon as you are done washing. CarPro HydroFoam should be diluted 1:9 and can be used by hand or with a foaming device. We recommend using an HP Pressure Washer Foam Cannon for best results. Wash and Coat in single step!
