Just wondering what techniques yous use for each and any tips or tricks? I seem to spend an eternity rinsing the hydrophobic and a tank of water would last me no time if I'd a big run of houses with this type of glass. I'm wondering if I'm over doing it on the rinsing but I suppose it's better rinsed off well and no complaints from the customers. Do yous spend a lot longer rinsing hydrophic?
