While you can use it on the whole car, normally you only use it to soak the really dirty areas, which are normally the lower panels, they tend to get all the mud and grime while the top normally isn't too bad. We recommend only using it where you need to as this saves time and product, which is normally the lower panels, and then use a normal ph-neutral snow foam across the whole car later.
Isn't it ph-neutral?
why don't you put it on the upper panels of the car?
