In the second delivery I filled the Gloria with 1000ml of water and 15ml ValetPro SnowFoam and am very happy with the foaming. Strong foam, wide-ranging. Depending on the nozzle used can be mixed to foam and set it as liquid and more more or less water.
Unfortunately, the limited spraying time is quite short by about 7-10 seconds, especially since it in 5-6 seconds is already beginning "spit" to!
So to lather the whole car I have to pump additional approximately 5-6 times! However, this one liter is sufficient, depending on nozzle used for the whole car (in my case an average sports coupe)!
