i think im a zaino addict. autoglym doesnt really sud up that well for me.
i thought the suds are there to help you glide along the paint for safer cleaning.
DoDo SN doesnt produce hardly any suds yet is by far one of the slickest shampoos i have used... and i have used quite a few.
The thing is... there are a hell of a lot of shampoos out there (in bulk sizes) which seem to offer excellent value for money but are actually full of thickening agents and water which offer nothing to the cleaning abilities.
I am keen to try Zaino Z7 though as i have the rest of the Z2 protection kit and a few other bits n pieces of theirs.
