Has anyone done a comparison test or had a wide experience with various car wash soaps? Does it even really matter that much? Obviously you simply want high lubricity, and hopefully no "extras" like added-in waxes. I'd like to know if you've found any differences between brands (not just "I use this and it's good").
My surprisingly long-lasting bottle of
Zaino Z7 is almost empty. I do have a full small bottle of
Sonus Gloss that I assume is also decent (a freebie that I have yet to try). I'm sure many will recommend
Prima Mystique. But I believe Octaneguy simply uses
Meguires Gold class which is much cheaper than the others and leads me to believe there's no need to go for the enthusiasts brands.
