Clearly recommended!

Just great - also works for many applications even without problems.
The often described "short" spraying time of 5-7 seconds is in my opinion is by no problem, you have to stop often pumps if you want to "soak" the whole car. In holding the container fits now not so much (liquid and air connectors) as the "big brother" FM50.
Very good for the variation are the 3 supplied nozzle, so to obtain the desired foaming depending on the mixing ratio. Initially, of course you have something to experiment until you has the "right" mix found.

My recommendation: 5ml shampoo / 12ml SnowFoam (or other foam generator) / 1 L of distilled water

One should also bear in mind that with the FM10 takes place BEFORE treatment and not after rinsing a completely clean car gets to have hand created without self.
As prewash absolutely top !!!
