Auto-Foam is a new generation premium quality, foaming water-based pre-wash treatment, designed to soak and saturate soiled vehicle paintwork prior to the application of vehicle shampoo and paint food. Auto-Foam is gentle too, and is for use with all pressure washer foam lances. Applied at a typical PIR (Panel Impact Ratio) of 4%, Auto-Foam will panel-dwell for typically five minutes. Auto-Foam is formulated specifically to offer maximum wetting and it rinses easily too. It is not designed as a superficial high foam product, but as a functional material.
